  3. CVE-2024-26925
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.

No CVSS.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: netfilter: nf_tables: libera mutex después de nft_gc_seq_end de la ruta de cancelación. El mutex de confirmación no debe liberarse durante la sección crítica entre nft_gc_seq_begin() y nft_gc_seq_end(); de lo contrario, el trabajador asíncrono de GC podría recopilar objetos caducados y obtener el bloqueo de confirmación liberado dentro de la misma secuencia de GC. nf_tables_module_autoload() libera temporalmente el mutex para cargar las dependencias del módulo, luego vuelve a reproducir la transacción nuevamente. Muévalo al final de la fase de cancelación después de llamar a nft_gc_seq_end().
