How to fix?

Upgrade torvalds/linux to version 5.10.273, 5.15.224, 6.1.167, 6.6.130, 6.12.78, 6.18.20, 6.19.10 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure in the nfnetlink_hook process. An attacker can gain access to sensitive kernel memory contents and potentially execute arbitrary code by triggering a use-after-free condition through concurrent manipulation of flowtable hooks and dumping operations.

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
