Descriptions
In the Linux kernel, the following vulnerability has been resolved:
blk-mq: make sure active queue usage is held for bio_integrity_prep()
blk_integrity_unregister() can come if queue usage counter isn't held
for one bio with integrity prepared, so this request may be completed with
calling profile->complete_fn, then kernel panic.
Another constraint is that bio_integrity_prep() needs to be called
before bio merge.
Fix the issue by:
- call bio_integrity_prep() with one queue usage counter grabbed reliably
- call bio_integrity_prep() before bio merge
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: blk-mq: asegúrese de que el uso de la cola activa se mantenga para bio_integrity_prep() blk_integrity_unregister() puede aparecer si el contador de uso de la cola no se mantiene para una biografía con integridad preparada, por lo que esta solicitud se puede completar llamando al perfil->complete_fn, luego kernel panic. Otra restricción es que es necesario llamar a bio_integrity_prep() antes de la fusión biológica. Solucione el problema de la siguiente manera: - llame a bio_integrity_prep() con un contador de uso de cola capturado de manera confiable - llame a bio_integrity_prep() antes de fusionar la biografía
