Title
fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath
Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath
When cifs_sanitize_prepath is called with an empty string or a string
containing only delimiters (e.g., "/"), the current logic attempts to
check *(cursor2 - 1) before cursor2 has advanced. This results in an
out-of-bounds read.
This patch adds an early exit check after stripping prepended
delimiters. If no path content remains, the function returns NULL.
The bug was identified via manual audit and verified using a
standalone test case compiled with AddressSanitizer, which
triggered a SEGV on affected inputs.

"value": "AV:N - A malicious SMB/DFS server can influence referral target path handling that flows through SMB client mount/DFS processing into `cifs_sanitize_prepath`. The triggering data is delivered over the network via SMB responses.\nAC:L - The trigger is a deterministic empty or delimiter-only prepath condition; no race or hard-to-control environmental condition is required. A malicious server or local mount caller can craft the relevant path form directly.\nPR:N - In the network scenario, the attacker only needs to operate the SMB/DFS endpoint that the victim client contacts and needs no privileges on the victim system. Local user-namespace reachability also exists before the final non-`FS_USERNS_MOUNT` mount denial, but the no-privilege malicious-server scenario is more severe.\nUI:R - The victim must initiate or otherwise cause an SMB/CIFS mount or DFS traversal to the attacker-controlled server. After that action, no further interaction is needed.\nS:U - The bug corrupts or reads kernel memory within the same host kernel security authority. It does not cross a separate scope such as a hypervisor, guest boundary, or IOMMU boundary.\nC:H - The immediate invalid access is a bounded read, but the same edge case can enter a path that treats memory before the prepath as part of the buffer, making this defensibly kernel memory corruption. Under the required overestimation rule, potential exploitation of kernel memory corruption is scored as high confidentiality impact.\nI:H - After the out-of-bounds read, if the preceding byte is a delimiter the old code decrements the cursor and writes a NUL before the prepath buffer. That conditional out-of-bounds write is kernel memory corruption and is scored as high integrity impact.\nA:H - The fix commit reports an AddressSanitizer SEGV on affected inputs, and the kernel path can produce invalid memory access or heap corruption. A repeatable kernel oops/panic or destabilization is therefore a high availability impact."

Threats
Impact
Moderate
A flaw was found in the Linux kernel on ARM processors. A race condition in Translation Lookaside Buffer Invalidation (TLBI) operations during memory permission changes allows a local attacker to write to memory resources owned by higher privilege levels. This could allow an unprivileged local attacker to gain kernel privileges or a guest VM to escape to the hypervisor, resulting in complete system compromise.

Threats
Impact
Important
A flaw was found in the Kernel-based Virtual Machine (KVM) for x86. This vulnerability occurs when KVM incorrectly re-checks Level 1 (L1) intercepts during the completion of userspace I/O emulation for a Level 2 (L2) instruction. If the L1 or host userspace modifies I/O interception settings during this process, KVM may misinterpret already-emulated I/O as intercepted. This can lead to a kernel warning and potentially disrupt the guest virtual machine, resulting in a denial of service. Exploitation requires local access to /dev/kvm and the ability to perform nested virtualization or manipulate I/O bitmaps.

Threats
Impact
Moderate
A flaw was found in AMD Zen 2-based processors, affecting components such as the kernel and Xen hypervisor. Improper isolation of shared resources within the CPU operation cache could allow an attacker to corrupt instructions executed at a different privilege level. This could potentially result in privilege escalation, granting an attacker higher system access than intended.

A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-only exports. This could allow modification of SMB-visible file behavior, including converting files into symbolic links or other reparse point types.

A flaw was found in Samba’s vfs_worm module. The module is intended to provide write-once, read-many (WORM) protections by preventing modification of files after a configurable grace period. Due to insufficient validation during rename operations, an authenticated user with write access to a share could overwrite a protected file by renaming a newly created file over the existing WORM-protected file.

A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.

A flaw was found in Samba. A remote attacker can exploit a misconfiguration in Samba file servers and classic domain controllers that use the "check password script" feature. If this script is configured with the %u substitution character, the client-controlled username is passed without proper escaping of shell meta-characters. This vulnerability allows an attacker to achieve remote command execution on the affected system. This issue primarily affects non-standard configurations where the "check password script" is used with %u and the samba-dcerpcd service is started as a system service.

A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length field remains consistent across all fragments of the same logical message. An attacker can exploit this by sending crafted DTLS fragments with conflicting message_length values, causing the implementation to allocate a buffer based on a smaller initial fragment and subsequently write beyond its bounds using larger, inconsistent fragments. Because the merge operation does not enforce proper bounds checking against the allocated buffer size, this results in an out-of-bounds write on the heap. The vulnerability is remotely exploitable without authentication via the DTLS handshake path and can lead to application crashes or potential memory corruption.

Threats
Impact
Important
A flaw was found in Vim. When decompressing .tgz archives, the Vimuntar function builds shell commands using shellescape() without the {special} flag. This allows a specially crafted archive filename to trigger Vim cmdline-special expansion and execute arbitrary commands in the context of the current user.

Threats
Impact
Moderate
A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.

In that file, disable nested virtualization for the `kvm_intel` and `kvm_amd` kernel modules:\n```\noptions kvm-intel nested=0\noptions kvm-amd nested=0\n```\n\nUse `lsmod` to determine if either module is already loaded. If so, remove loaded modules with `modprobe -r`. To validate that nested virtualization is disabled, read the files `/sys/module/kvm_intel/parameters/nested` and `/sys/module/kvm_amd/parameters/nested`. If these modules are loaded, those files should read `N` to indicate that the feature is disabled.\n\nIn OpenShift 4, a MachineConfig can be utilized to create a modprobe configuration allowing control of the module on applicable nodes.

"text": "This issue is particularly important because it affects the correct enforcement of X.509 nameConstraints, which are specifically designed to limit the authority of subordinate CAs. In GnuTLS, the use of case-sensitive comparisons (memcmp) for dNSName and the domain portion of rfc822Name violates the case-insensitive matching requirements defined in RFC 5280 and RFC 4343. As a result, a constrained subordinate CA can bypass excludedSubtrees or permittedSubtrees restrictions simply by changing the letter casing of a domain in the SAN (e.g., ExAmPlE.CoM vs example.com). Since nameConstraints are often the only mechanism enforcing domain boundaries in delegated PKI hierarchies, this flaw effectively allows a malicious or compromised sub-CA to issue certificates for domains that should be cryptographically prohibited, enabling unauthorized certificate validation and potential TLS impersonation of restricted services.",

Regarding Attack Vector and Privileges Required, Red Hat assesses these elements as Local and Low respectively, as remote unauthenticated exploitation would require all the conditions above in a library client that listened on a network port and processed attacker-controllable data with the affected library functions.",

The vulnerability can be triggered by an unauthenticated attacker sending crafted DTLS handshake fragments, requiring no prior access or interaction. It leads to an out-of-bounds read caused by an integer underflow in fragment reassembly, operating entirely on attacker-controlled input. Such flaws in low-level protocol parsing are particularly serious, as they may result in disclosure of sensitive process memory, including cryptographic or session-related data, and can also cause reliable application crashes leading to denial of service. Given that DTLS is commonly used in network-facing services such as VPNs and real-time communication systems, the exposure surface is broad. The combination of unauthenticated remote exploitation, memory safety violation, and potential confidentiality and availability impact justifies classifying this issue as high severity rather than moderate.",

"text": "A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length field remains consistent across all fragments of the same logical message. An attacker can exploit this by sending crafted DTLS fragments with conflicting message_length values, causing the implementation to allocate a buffer based on a smaller initial fragment and subsequently write beyond its bounds using larger, inconsistent fragments. Because the merge operation does not enforce proper bounds checking against the allocated buffer size, this results in an out-of-bounds write on the heap. The vulnerability is remotely exploitable without authentication via the DTLS handshake path and can lead to application crashes or potential memory corruption.",

"text": "This vulnerability should be classified as an important flaw rather than moderate because it exposes a pre-authentication, remotely reachable heap buffer overflow in the DTLS handshake processing path, which is part of the core protocol handling logic and commonly exposed in network-facing services. The flaw enables an attacker to inject controlled data at attacker-chosen offsets and sizes beyond allocated heap boundaries by exploiting inconsistent message_length handling across fragments, effectively creating a constrained but meaningful heap write primitive. Unlike benign memory safety bugs, this condition is deterministically triggerable with a small number of crafted packets and no environmental dependencies for denial-of-service, and it targets a long-lived parsing state where memory corruption can affect adjacent heap structures. Even if reliable code execution requires additional heap manipulation or layout knowledge, the combination of remote reachability, lack of authentication, controlled memory corruption capability, and trivial crashability significantly elevates the risk profile beyond moderate severity. In real-world deployments, such primitives are often sufficient to enable heap grooming and exploitation chains, particularly in services that repeatedly process attacker-controlled input, making this a materially important security flaw.",

A flaw was found in the Linux kernel's CIFS (Common Internet File System) client. When the `cifs_sanitize_prepath` function processes specially crafted input, such as an empty string or a string containing only delimiters, it can attempt to read data beyond its allocated memory buffer. This out-of-bounds read can lead to a system crash, resulting in a denial of service.

Topic: An update for multiple packages is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: This is a kernel live patch module which can be loaded by the kpatch command line utility to modify the code of a running kernel. This patch module is targeted for kernel-4.18.0-553.53.1.el8_10.
Security Fix(es):
* kernel: fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath (CVE-2026-43112)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Terms of Use: This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/). If you distribute this content, or a modified version of it, you must provide attribution to Red Hat Inc. and provide a link to the original.
A flaw was found in the Linux kernel's CIFS (Common Internet File System) client. When the `cifs_sanitize_prepath` function processes specially crafted input, such as an empty string or a string containing only delimiters, it can attempt to read data beyond its allocated memory buffer. This out-of-bounds read can lead to a system crash, resulting in a denial of service.

A flaw was found in the Linux kernel's CIFS (Common Internet File System) client. When the `cifs_sanitize_prepath` function processes specially crafted input, such as an empty string or a string containing only delimiters, it can attempt to read data beyond its allocated memory buffer. This out-of-bounds read can lead to a system crash, resulting in a denial of service.

Threats
Impact
Important
A flaw was found in the Linux kernel's netfilter component, specifically within the `nft_set_pipapo_avx2` AVX2 matching functions. This vulnerability occurs when a `pipapo` set with an 'ipv4 . port' key is reloaded. Due to incorrect masking, the system may erroneously identify non-matching elements as duplicates, leading to data integrity issues and unexpected behavior. A remote attacker could potentially exploit this to cause a denial of service or impact data integrity.

Threats
Impact
Important
A flaw was found in the Linux kernel's networking scheduler. A race condition, which is a problem that occurs when multiple operations try to access the same resource at the same time, exists when network filter operations are run concurrently. This can lead to a Use-After-Free (UAF) vulnerability, where the system attempts to use memory that has already been released. This could potentially allow an attacker to cause system instability or execute arbitrary code.

A flaw was found in the Linux kernel's nf_tables component. A logic bug in nft_map_catchall_activate causes an inverted element activity check during the abort path of a failed transaction. This can lead to a use-after-free vulnerability, as catchall verdict elements may still reference a freed chain. A local low privileged user can exploit this to cause a denial of service or potentially achieve privilege escalation.

Threats
Impact
Important
A flaw was found in the Linux kernel's CIFS (Common Internet File System) client. When the `cifs_sanitize_prepath` function processes specially crafted input, such as an empty string or a string containing only delimiters, it can attempt to read data beyond its allocated memory buffer. This out-of-bounds read can lead to a system crash, resulting in a denial of service.

Threats
Impact
Important
A flaw was found in the Linux kernel's netfilter component, specifically within the `nft_set_pipapo_avx2` AVX2 matching functions. This vulnerability occurs when a `pipapo` set with an 'ipv4 . port' key is reloaded. Due to incorrect masking, the system may erroneously identify non-matching elements as duplicates, leading to data integrity issues and unexpected behavior. A remote attacker could potentially exploit this to cause a denial of service or impact data integrity.

Threats
Impact
Important
A flaw was found in the Linux kernel's Generic Receive Offload (GRO) networking subsystem. This vulnerability occurs when `skb_gro_receive()` attempts to merge zerocopy socket buffers (skbs) without properly managing page reference counts, specifically when the `SKBFL_MANAGED_FRAG_REFS` flag is set. An attacker could potentially exploit this to trigger a Use-After-Free (UAF) condition, which is a memory corruption vulnerability that can lead to system instability or potentially arbitrary code execution.

Threats
Impact
Important
A flaw was found in the Linux kernel's networking scheduler. A race condition, which is a problem that occurs when multiple operations try to access the same resource at the same time, exists when network filter operations are run concurrently. This can lead to a Use-After-Free (UAF) vulnerability, where the system attempts to use memory that has already been released. This could potentially allow an attacker to cause system instability or execute arbitrary code.

A logic bug in nft_map_catchall_activate causes an inverted element activity check during the abort path of a failed transaction.

A local low privileged user can exploit this to cause a denial of service or potentially achieve privilege escalation.",

"text": "A logic bug in nf_tables nft_map_catchall_activate uses an inverted element active check during the abort path of a failed transaction. This can prevent re activation of catchall map elements and for NFT_GOTO verdict elements it can skip restoring the chain use reference count. Repeating an abort sequence can permanently decrement chain use until DELCHAIN frees the chain while catchall elements still reference it which can result in a use after free. For the CVSS the PR is L, but in the paranoid scenario the unprivileged users may reach nf_tables via user namespaces with delegated CAP_NET_ADMIN. The issue is not directly network reachable and is triggered by local nftables control plane operations. Impact can range from denial of service to potential privilege escalation depending on heap reuse.",

A flaw was found in the Linux kernel's CIFS (Common Internet File System) client. When the `cifs_sanitize_prepath` function processes specially crafted input, such as an empty string or a string containing only delimiters, it can attempt to read data beyond its allocated memory buffer. This out-of-bounds read can lead to a system crash, resulting in a denial of service.

Threats
Impact
Important
A flaw was found in the Linux kernel's netfilter component, specifically within the `nft_set_pipapo_avx2` AVX2 matching functions. This vulnerability occurs when a `pipapo` set with an 'ipv4 . port' key is reloaded. Due to incorrect masking, the system may erroneously identify non-matching elements as duplicates, leading to data integrity issues and unexpected behavior. A remote attacker could potentially exploit this to cause a denial of service or impact data integrity.

Threats
Impact
Important
A flaw was found in the Linux kernel's Generic Receive Offload (GRO) networking subsystem. This vulnerability occurs when `skb_gro_receive()` attempts to merge zerocopy socket buffers (skbs) without properly managing page reference counts, specifically when the `SKBFL_MANAGED_FRAG_REFS` flag is set. An attacker could potentially exploit this to trigger a Use-After-Free (UAF) condition, which is a memory corruption vulnerability that can lead to system instability or potentially arbitrary code execution.

Threats
Impact
Important
A flaw was found in the Linux kernel's futex subsystem. The need_futex_hash_allocate_default() function incorrectly relies on CLONE_THREAD semantics, which can lead to non-concurrency issues when memory allocations (mm->futex_ref pcpu allocations) are shared across CLONE_VM clones, excluding vfork(). This can result in a use-after-free vulnerability in futex_hash_put, a form of memory corruption. Such vulnerabilities can potentially lead to system instability or other security impacts.

Threats
Impact
Important
A flaw was found in the Linux kernel's networking scheduler. A race condition, which is a problem that occurs when multiple operations try to access the same resource at the same time, exists when network filter operations are run concurrently. This can lead to a Use-After-Free (UAF) vulnerability, where the system attempts to use memory that has already been released. This could potentially allow an attacker to cause system instability or execute arbitrary code.

Notes
Topic: An update for multiple packages is now available for Red Hat Enterprise Linux 9.6 Extended Update Support.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: This is a kernel live patch module which can be loaded by the kpatch command line utility to modify the code of a running kernel. This patch module is targeted for kernel-5.14.0-570.17.1.el9_6.
Security Fix(es):
* kernel: Kernel: Privilege escalation or denial of service in nf_tables via inverted element activity check (CVE-2026-23111)
* kernel: netfilter: nft_set_pipapo_avx2: don't return non-matching entry on expiry (CVE-2026-43114)
* kernel: fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath (CVE-2026-43112)
* kernel: Linux kernel: Use-After-Free in net/gro due to improper handling of zerocopy skbs (CVE-2026-46323)
* kernel: net/sched: act_api: use RCU with deferred freeing for action lifecycle (CVE-2026-53264)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A flaw was found in the Linux kernel's nf_tables component. A logic bug in nft_map_catchall_activate causes an inverted element activity check during the abort path of a failed transaction. This can lead to a use-after-free vulnerability, as catchall verdict elements may still reference a freed chain. A local low privileged user can exploit this to cause a denial of service or potentially achieve privilege escalation.

Threats
Impact
Important
A flaw was found in the Linux kernel's CIFS (Common Internet File System) client. When the `cifs_sanitize_prepath` function processes specially crafted input, such as an empty string or a string containing only delimiters, it can attempt to read data beyond its allocated memory buffer. This out-of-bounds read can lead to a system crash, resulting in a denial of service.

Threats
Impact
Important
A flaw was found in the Linux kernel's netfilter component, specifically within the `nft_set_pipapo_avx2` AVX2 matching functions. This vulnerability occurs when a `pipapo` set with an 'ipv4 . port' key is reloaded. Due to incorrect masking, the system may erroneously identify non-matching elements as duplicates, leading to data integrity issues and unexpected behavior. A remote attacker could potentially exploit this to cause a denial of service or impact data integrity.

Threats
Impact
Important
A flaw was found in the Linux kernel's Generic Receive Offload (GRO) networking subsystem. This vulnerability occurs when `skb_gro_receive()` attempts to merge zerocopy socket buffers (skbs) without properly managing page reference counts, specifically when the `SKBFL_MANAGED_FRAG_REFS` flag is set. An attacker could potentially exploit this to trigger a Use-After-Free (UAF) condition, which is a memory corruption vulnerability that can lead to system instability or potentially arbitrary code execution.

Threats
Impact
Important
A flaw was found in the Linux kernel's networking scheduler. A race condition, which is a problem that occurs when multiple operations try to access the same resource at the same time, exists when network filter operations are run concurrently. This can lead to a Use-After-Free (UAF) vulnerability, where the system attempts to use memory that has already been released. This could potentially allow an attacker to cause system instability or execute arbitrary code.

This can lead to a use-after-free vulnerability, as catchall verdict elements may still reference a freed chain. A local low privileged user can exploit this to cause a denial of service or potentially achieve privilege escalation.",

"text": "A logic bug in nf_tables nft_map_catchall_activate uses an inverted element active check during the abort path of a failed transaction. This can prevent re activation of catchall map elements and for NFT_GOTO verdict elements it can skip restoring the chain use reference count. Repeating an abort sequence can permanently decrement chain use until DELCHAIN frees the chain while catchall elements still reference it which can result in a use after free. For the CVSS the PR is L, but in the paranoid scenario the unprivileged users may reach nf_tables via user namespaces with delegated CAP_NET_ADMIN. The issue is not directly network reachable and is triggered by local nftables control plane operations. Impact can range from denial of service to potential privilege escalation depending on heap reuse.",

This vulnerability occurs when a `pipapo` set with an \u0027ipv4 . port\u0027 key is reloaded. Due to incorrect masking, the system may erroneously identify non-matching elements as duplicates, leading to data integrity issues and unexpected behavior. A remote attacker could potentially exploit this to cause a denial of service or impact data integrity.",

A flaw was found in the Linux kernel's CIFS (Common Internet File System) client. When the `cifs_sanitize_prepath` function processes specially crafted input, such as an empty string or a string containing only delimiters, it can attempt to read data beyond its allocated memory buffer. This out-of-bounds read can lead to a system crash, resulting in a denial of service.

Threats
Impact
Important
A flaw was found in the Linux kernel's netfilter component, specifically within the `nft_set_pipapo_avx2` AVX2 matching functions. This vulnerability occurs when a `pipapo` set with an 'ipv4 . port' key is reloaded. Due to incorrect masking, the system may erroneously identify non-matching elements as duplicates, leading to data integrity issues and unexpected behavior. A remote attacker could potentially exploit this to cause a denial of service or impact data integrity.

Threats
Impact
Important
A flaw was found in the Linux kernel's Generic Receive Offload (GRO) networking subsystem. This vulnerability occurs when `skb_gro_receive()` attempts to merge zerocopy socket buffers (skbs) without properly managing page reference counts, specifically when the `SKBFL_MANAGED_FRAG_REFS` flag is set. An attacker could potentially exploit this to trigger a Use-After-Free (UAF) condition, which is a memory corruption vulnerability that can lead to system instability or potentially arbitrary code execution.

Threats
Impact
Important
A flaw was found in the Linux kernel's futex subsystem. The need_futex_hash_allocate_default() function incorrectly relies on CLONE_THREAD semantics, which can lead to non-concurrency issues when memory allocations (mm->futex_ref pcpu allocations) are shared across CLONE_VM clones, excluding vfork(). This can result in a use-after-free vulnerability in futex_hash_put, a form of memory corruption. Such vulnerabilities can potentially lead to system instability or other security impacts.

Threats
Impact
Important
A flaw was found in the Linux kernel's networking scheduler. A race condition, which is a problem that occurs when multiple operations try to access the same resource at the same time, exists when network filter operations are run concurrently. This can lead to a Use-After-Free (UAF) vulnerability, where the system attempts to use memory that has already been released. This could potentially allow an attacker to cause system instability or execute arbitrary code.
