CVE-2026-31507

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SMC module. A local user can exploit this vulnerability by using the tee2 system call to duplicate a splice pipe buffer, leading to a double-free condition. This double-free can result in a use-after-free error and a kern...

USN-8201-1: Linux kernel (Azure) vulnerabilities

Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module LSM. An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor profiles causing denial of service, exposure of sensitive information kernel memory, local...

CVE-2026-31486

A flaw was found in the Linux kernel's hwmon subsystem, specifically within the pmbus/core module. The regulator operations, which manage power management bus PMBus registers and shared data, were not adequately protected by a mutex a mechanism to prevent simultaneous access to shared resources...

DRUPAL-CONTRIB-2026-033

This module enables you to obfuscate email addresses in content. The module doesn't sufficiently sanitize user input via the Twig filter. This vulnerability is mitigated by the fact that it only affects sites using the ROT13 encoding and where an attacker can enter content that is filtered using...

CVE-2026-35368

A vulnerability exists in the chroot utility of uutils coreutils when using the --userspec option. The utility resolves the user specification via getpwnam after entering the chroot but before dropping root privileges. On glibc-based systems, this can trigger the Name Service Switch NSS to load...

CVE-2026-35362

The safetraversal module in uutils coreutils, which provides protection against Time-of-Check to Time-of-Use TOCTOU symlink races using file-descriptor-relative syscalls, is incorrectly limited to Linux targets. On other Unix-like systems such as macOS and FreeBSD, the utility fails to utilize...

CVE-2026-35352

A Time-of-Check to Time-of-Use TOCTOU race condition exists in the mkfifo utility of uutils coreutils. The utility creates a FIFO and then performs a path-based chmod to set permissions. A local attacker with write access to the parent directory can swap the newly created FIFO for a symbolic link...

CVE-2026-31521

The CVE-2026-31521 issue is in the Linux kernel module loader’s simplify_symbols() where an out-of-bounds st_shndx (eg SHN_XINDEX) could cause a kernel panic. The patch adds validation of st_shndx against the valid range before using it, preventing the potential crash. Several OSV entries (Debian...

CVE-2026-31433

A flaw was found in the ksmbd module of the Linux kernel. A remote attacker can exploit this vulnerability by sending a specially crafted compound request, specifically a combination of QUERYDIRECTORY and QUERYINFO. Due to a missing validation check for the client-provided output buffer length, a...

kernel: Linux kernel: Use-after-free in bonding module can cause system crash or arbitrary code execution

A flaw was found in the Linux kernel's bonding module. This use-after-free vulnerability occurs when a new slave device is added to the bonding array but fails during the enslave process. A local attacker can exploit this by triggering the enslave failure, which may lead to a system crash,...

kernel: smc: Use __sk_dst_get() and dst_dev_rcu() in smc_clc_prfx_match()

A flaw was found in the Linux kernel’s SMC Shared Memory Communication module: in smcclcprfxmatch, the function is called from smclistenwork without proper RCU or RTNL protection. The code previously used skdstgetsk-dev, which can lead to a use-after-free UAF condition if the sk’s destination is...
