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.
