Affected: Linux Kernel

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.

 https://vulnerability.circl.lu/vuln/usn-6576-1 USN-6576-1 — linux-oem-6.1 vulnerability 2026-10-01T15:15:10.054855+00:00

Affected: Ubuntu:22.04:LTS: linux-oem-6.1

Lonial Con discovered that the netfilter subsystem in the Linux kernel did not properly handle an expired catchall element in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
