Release Mutex After Nft_gc_seq_end from Abort Path

Summary

The vulnerability CVE-2024-26925 affects the Linux kernel and involves the netfilter nf_tables. It allows for the release of mutex after nft_gc_seq_end from the abort path, potentially leading to the async GC worker collecting expired objects and obtaining the released commit lock within the same GC sequence. The vulnerability has been identified as exploited, but there is no information about ransomware groups leveraging it. The resolution for this vulnerability involves moving nf_tables_module_autoload() at the end of the abort phase after nft_gc_seq_end() is called.
