netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path
MEDIUM 5.5EPSS 0.3%
In the Linux kernel, the following vulnerability has been resolved:netfilter: nf_tables: release mutex after nft_gc_seq_end from abort pathThe commit mutex should not be released during the critical sectionbetween nft_gc_seq_begin() and nft_gc_seq_end(), otherwise, async GCworker could collect expired objects and get the released commit lockwithin the same GC sequence.nf_tables_module_autoload() temporarily releases the mutex to loadmodule dependencies, then it goes back to replay the transaction again.Move it at the end of the abort phase after nft_gc_seq_end() is called.
