CVE-2023-6111

HIGH

Linux Kernel 5.15.134-5.15.139 - Use-After-Free in nf_tables Catchall Set Element

Title source: llm
STIX 2.1

Description

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.
