kernel: netfilter: use-after-free in nft_trans_gc_catchall_sync leads to privilege escalation
A use-after-free flaw was found in the netfilter subsystem of the Linux kernel. If the catchall element is garbage-collected when the pipapo set is removed, the element can be deactivated twice. This can cause a use-after-free issue on an NFTCHAIN object or NFTOBJECT object, allowing a local...
