kernel: drm/drm_file: Fix pid refcounting race

A race condition was found in the Linux kernel. The rmfileupdatepid only increments the refcount of a struct pid after storing a pointer to it in filp-pid, dropping the dev-filelistmutex, resulting in a use-after-free vulnerability...

kernel: netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path

A flaw was found in the Linux kernel’s Netfilter nftables module. The issue arises from improper mutex handling during the garbage collection GC process. The problem occurs between the critical functions nftgcseqbegin and nftgcseqend, where a mutex lock is incorrectly released too early, leading ...
