netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path

published 2024-04-24 2 y ago modified 2026-10-15 25 d ago also EUVD-2024-24187

cvss: 7.8; version 3.1, CNA

epss: 0.3%; EPSS 0.3% chance of exploitation in 30 days, percentile 18%
public exploits: 0; none known

In the Linux kernel, the following vulnerability has been resolved:

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.
