How to fix?

Upgrade torvalds/linux to version 5.10.265, 5.15.216, 6.1.183, 6.6.148, 6.12.101, 6.18.42, 7.1.6 or higher.

Overview

Affected versions of this package are vulnerable to NULL Pointer Dereference in the xfrm_hash_rebuild process. An attacker can cause a system crash and potential denial of service by triggering memory allocation failures during policy reinsertion, leading to a NULL pointer dereference and kernel panic under memory pressure.

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
