Description

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.

Affected configurations

• linux linux kernel (>= 4.19.312 < 4.19.316) • linux linux kernel (>= 5.4.274 < 5.4.278) • linux linux kernel (>= 5.10.215 < 5.10.219) • linux linux kernel (>= 5.15.154 < 5.15.161) • linux linux kernel (>= 6.1.84 < 6.1.94) • linux linux kernel (>= 6.6.24 < 6.6.34) • linux linux kernel (>= 6.9 < 6.9.5)
