Descriptions
In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak
Using completion_done to determine whether the caller has gone
away only works after a complete call. Furthermore it's still
possible that the caller has not yet called wait_for_completion,
resulting in another potential UAF.
Fix this by making the caller use cancel_work_sync and then freeing
the memory safely.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: crypto: qat: corrige la pérdida de memoria ADF_DEV_RESET_SYNC. El uso de complete_done para determinar si la persona que llama se ha ido solo funciona después de una llamada completa. Además, aún es posible que la persona que llama aún no haya llamado a wait_for_completion, lo que genera otra posible UAF. Solucione este problema haciendo que la persona que llama use cancel_work_sync y luego liberando la memoria de forma segura.
