CVE-2026-46104

CVE-2026-46104 affects the Linux kernel where SELinux socket state is stored in the composite LSM socket blob. The vulnerability arises in sock_has_perm() and nlmsg_sock_has_extended_perms(), which currently dereference sk->sk_security directly, assuming the SELinux blob is at offset zero. In ...

CVE-2024-41012 filelock: Remove locks reliably when fcntl/close race is detected

In the Linux kernel, the following vulnerability has been resolved: filelock: Remove locks reliably when fcntl/close race is detected When fcntlsetlk races with close, it removes the created lock with dolockfilewait. However, LSMs can allow the first dolockfilewait that created the lock while...

CVE-2024-41012

CVE-2024-41012 (Linux kernel) describes a filelock race where fcntl_setlk() races with close() and a second path in posix_lock_file() could fail to remove a lock. In certain LSMs this could let a created lock survive a competing removal, enabling use-after-free reads in /proc/locks and potentiall...

Design/Logic Flaw

containerd is a container runtime. A bug was found in containerd versions prior to 1.4.8 and 1.5.4 where pulling and extracting a specially-crafted container image can result in Unix file permission changes for existing files in the host’s filesystem. Changes to file permissions can deny access t...
