CVE-2024-26925

netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path

State: Published
Severity: 7.8 High
Published: Apr 24, 2024
Updated: Oct 15, 2026

Description

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.
