Description SMASH SMASH 2023-10-02 07:41:21 UTC

This vulnerability allows local attackers to disclose sensitive information on
affected installations of the Linux Kernel. An attacker must first obtain the
ability to execute high-privileged code on the target system in order to exploit
this vulnerability.

The specific flaw exists within the u32_match_it function. The issue results
from the lack of proper validation of user-supplied data, which can result in a
read past the end of an allocated data structure. An attacker can leverage this
in conjunction with other vulnerabilities to execute arbitrary code in the
context of the kernel.

Comment 1 Carlos López 2023-10-02 07:47:24 UTC

Fix:
https://lore.kernel.org/all/20230828132107.18376-1-wander@redhat.com/

Introduced in 1b50b8a371e9 ("[NETFILTER]: Add u32 match"), which comes from v2.6.23, so all branches should be affected.

Comment 2 Chester Lin 2023-10-03 08:09:17 UTC

The fix has been merged since v6.6-rc1:
