Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path<br /> <br /> The commit mutex should not be released during the critical section<br /> between nft_gc_seq_begin() and nft_gc_seq_end(), otherwise, async GC<br /> worker could collect expired objects and get the released commit lock<br /> within the same GC sequence.<br /> <br /> nf_tables_module_autoload() temporarily releases the mutex to load<br /> module dependencies, then it goes back to replay the transaction again.<br /> Move it at the end of the abort phase after nft_gc_seq_end() is called.
