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. 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.

Affected configurations

• linux linux kernel (>= 5.15.134 < 5.15.140) • linux linux kernel (>= 6.1.56 < 6.1.64) • linux linux kernel (>= 6.5.6 < 6.5.13) • linux linux kernel (>= 6.6 < 6.6.3)
