How to fix?

Upgrade torvalds/linux to version 5.15.222, 6.1.189, 6.6.158, 6.12.112, 6.18.55, 7.2.9 or higher.

Overview

Affected versions of this package are vulnerable to Remote Code Execution (RCE) through improper management of XDP program pointers during channel resizing in the veth process. An attacker can execute arbitrary code or cause a kernel panic by triggering a channel resize operation that leaves stale pointers, leading to use-after-free conditions when NAPI is re-enabled.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
