Root has patched CVE-2022-0480 in the linux package for Root:Ubuntu:24.04. Multiple fixed versions available.

A flaw was found in the filelock_init in fs/locks.c function in the Linux kernel. This issue can lead to host memory exhaustion due to memcg not limiting the number of Portable Operating System Interface (POSIX) file locks.

The kernel packages contain the Linux kernel, the core of any Linux operating system.
