How to fix?

Upgrade torvalds/linux to version 5.10.261, 5.15.212, 6.1.178, 6.6.145, 6.12.97, 6.18.40, 7.1.5 or higher.

Overview

Affected versions of this package are vulnerable to Buffer Overflow in the bpf_msg_pop_data process. An attacker can cause out-of-bounds memory access and kernel memory corruption by supplying crafted values for the start and len parameters, leading to integer overflow and bypassing bounds checks. This can result in arbitrary code execution or denial of service by manipulating kernel memory structures through local access to a socket attached to a sockmap or kTLS.

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
