GHSA-XGR2-4F4Q-M3P9

Vulnerability from github – Published: 2023-11-14 15:30 – Updated: 2024-08-27 15:32

Details

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.

The function nft_trans_gc_catchall did not remove the catchall set element from the catchall_list when the argument sync is true, making it possible to free a catchall set element many times.

We recommend upgrading past commit 93995bf4af2c5a99e2a87f0cd5ce547d31eb7630.

Severity

7.8 (High)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
