CWE-416

Description

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Due to a race condition between nf_tables netlink control plane transaction and nft_set element garbage collection, it is possible to underflow the reference counter causing a use-after-free vulnerability. We recommend upgrading past commit 3e91b0ebd994635df2346353322ac51ce84ce6d8.

Affected configurations

• linux linux kernel (< 4.19.316) • linux linux kernel (>= 4.20 < 5.4.262) • linux linux kernel (>= 5.5 < 5.10.198) • linux linux kernel (>= 5.11 < 5.15.134) • linux linux kernel (>= 5.16 < 6.1.56) • linux linux kernel (>= 6.2.0 < 6.4.11) • debian debian linux 10.0
