Vulnerability Data
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path The commit mutex should not be released during the critical section between nft_gc_seq_begin() and nft_gc_seq_end(), otherwise, async GC worker could collect…

expired objects and get the released commit lock within the same GC sequence. nf_tables_module_autoload() temporarily releases the mutex to load module 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.

Security testing can detect race conditions and locking errors before release.
Secure development lifecycle includes concurrency and locking requirements that reduce improper locking defects.
Application security requirements can mandate proper lock acquisition/release patterns.
Secure architecture principles address thread-safety and resource synchronization.
Secure coding standards directly prohibit missing or incorrect lock usage.
Change management may catch locking issues introduced by modifications but does not prevent the weakness itself.
