CVE-2026-4878

A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation.

CVE-2026-35385

A flaw was found in OpenSSH. When the `scp` command is used by a root user to download a file with the legacy protocol option (`-O`) and without preserving original file permissions (`-p`), the downloaded file can be installed with elevated privileges (setuid or setgid). This unexpected behavior could allow a malicious file to execute with higher permissions than intended, posing a security risk through potential privilege escalation.

CVE-2026-35535

A flaw was found in Sudo. A local user could exploit a failure in the setuid, setgid, or setgroups calls, which are used to drop privileges before running the mailer. This oversight allows for privilege escalation, enabling the user to gain elevated access on the system.

CVE-2026-39979

A flaw was found in jq, a command line JSON processor, specifically in the libjq API. Parsing a malformed JSON input from a non-NUL-terminated buffer using the `jv_parse_sized` function can cause an out-of-bounds read, resulting in an application crash and a possible memory disclosure within the error message generated by the parser.

CVE-2026-40164

A flaw was found in jq, a command-line JSON processor. A remote attacker could exploit this vulnerability by providing a specially crafted JSON object. This object leverages a weakness in jq's hashing algorithm, which uses a hardcoded, publicly known seed. By crafting the JSON object to cause hash collisions, an attacker can degrade the performance of JSON object hash table operations, leading to significant CPU exhaustion and a denial of service (DoS) for systems processing the malicious JSON data.

CVE-2026-41035

A flaw was found in rsync. When rsync is configured to handle extended attributes (using the -X or --xattrs option), a remote attacker can exploit a use-after-free vulnerability. This occurs because the receive_xattr function incorrectly processes an untrusted length value during a sorting operation, leading to memory corruption. Successful exploitation can result in a denial of service, causing the rsync process to crash, and may potentially allow for arbitrary code execution.

A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash (denial of service) or potentially allow arbitrary code execution with kernel privileges.

CVE-2026-46300

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged binaries and gain root privileges.

CVE-2026-46331

A flaw was found in the Linux kernel's traffic control packet editing (pedit) subsystem. In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory. A local attacker with the ability to configure traffic control rules could exploit this to escalate privileges or crash the system.

This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory.
