Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

How this class of weakness works · CWE-667

Shared resources are accessed without correct locking, so concurrent operations interleave into inconsistent — and sometimes exploitable — states, or deadlock the service outright. These bugs are subtle and timing-dependent. The fix is correct, consistent locking or atomic operations around every shared resource.

Recommended fix High confidence

Linux kernel 5.15.155+, 5.10.215+, 5.4.274+, or 4.20+ (depending on your current branch)

  1. Upgrade the Linux kernel to version 5.15.155 or later for the 5.15 stable branch
  2. Upgrade the Linux kernel to version 5.10.215 or later for the 5.10 stable branch
  3. Upgrade the Linux kernel to version 5.4.274 or later for the 5.4 stable branch
  4. Upgrade the Linux kernel to version 4.20 or later for the 4.19 stable branch
  5. After kernel upgrade, reboot the system to load the fixed kernel
  6. Verify the fix is applied by checking the kernel version and confirming the patch 0d459e2ffb541841714839e8228b845458ed3b27 is included
Caveat Standard kernel upgrade risks apply - test in non-production environment first; some kernel configurations or modules may need rebuilding
