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.

Threats
Impact
Moderate
A flaw was found in Samba’s certificate auto-enrollment Group Policy handling. When certificate auto-enrollment is enabled, Samba may retrieve a CA certificate over an unencrypted HTTP connection and install it into the local trust store without proper verification. An attacker with the ability to intercept or redirect network traffic could exploit this behavior to supply a malicious certificate authority certificate, potentially allowing interception or spoofing of trusted communications.
8.0 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-2340
Threats
Impact
Important
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.
6.5 (Medium)
Affected products
Fixed
4 products, the same list as for
CVE-2026-2340
Threats
Impact
Moderate
A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP (Dynamic Host Configuration Protocol) options, such as a malicious hostname, to a system using dracut's legacy DHCP path. These options are improperly handled and written into temporary shell scripts without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs, potentially compromising the system's boot and network behavior.
7.5 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-2340
Threats
Impact
Important
A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.
7.5 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-2340
Threats
Impact
Moderate
A flaw was found in dracut. The die() error-handling function writes its message into a shell script under the initramfs emergency-hook directory without properly shell-quoting it. When the message contains data derived from the DHCP ROOT_PATH option, an attacker on the adjacent network who controls a rogue DHCP server can inject a command-substitution sequence that executes as root the next time dracut sources its emergency hook scripts during standard boot-failure handling.
7.5 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-2340
Threats
Impact
Important
A flaw was found in systemd, a system and service manager. An unprivileged user can exploit this vulnerability by making an Inter-Process Communication (IPC) API call with spurious data. In older versions (v249 and earlier), this can lead to stack overwriting with attacker-controlled content, potentially enabling arbitrary code execution or privilege escalation. In newer versions (v250 and later), the flaw causes systemd to assert and freeze, resulting in a Denial of Service (DoS).
7.8 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-2340
Threats
Impact
Moderate
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.
7.1 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-2340
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.

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.",

"text": "Red Hat Product Security has assessed this CVE as 7.5 CVSS with Moderate security Impact. This assessment reflects the library\u0027s typical deployment within enterprise software, where libarchive is frequently embedded into automated, network-accessible services that receive and process archives originating from remote sources. In these environments, a specially crafted RAR5 archive may be delivered and processed automatically without requiring direct user interaction, allowing a remote attacker to trigger the vulnerability and cause the affected application or service processing the archive to terminate unexpectedly, resulting in a denial of service.\n\nFrom a standalone library perspective, however, the vulnerable code is only reached when an application opens and processes a crafted RAR5 archive. Evaluating libarchive in isolation, without considering downstream deployment models, the vulnerability more closely aligns with a CVSS score of 5.5-CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H (Moderate), reflecting an Attack Vector of Local (AV:L) and User Interaction Required (UI:R). This is because the crafted archive must first be delivered to and processed by a local application before the vulnerable parsing logic is executed. \n\nRed Hat\u0027s assigned score instead reflects the operational deployment of libarchive in automated, network-facing workloads in downstream environment models rather than the standalone library in isolation.\n\n```\n\nThis vulnerability only affects libarchive releases that include support for the RAR5 archive format. RAR5 support was first introduced upstream in libarchive 3.4.0 (https://github.com/libarchive/libarchive/wiki/ReleaseNotes#libarchive-340). Earlier libarchive releases do not contain the vulnerable RAR5 parsing code and are therefore not affected.\n\nRed Hat Enterprise Linux 6, 7, and 8 ship Libarchive versions prior to v3.4.0 that do not include RAR5 support and are therefore not affected.\n\n```",

This can be achieved by blacklisting the module.\n\nCreate a file named `/etc/modprobe.d/blacklist-cifs.conf` with the following content:\n```\nblacklist cifs\n```\nAfter creating the file, regenerate the initramfs and reboot the system for the changes to take effect.\n```bash\ndracut -f -v\nreboot\n```\nDisabling the `cifs` module will prevent the system from mounting CIFS network shares, which may impact functionality relying on this protocol.",
