In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - ADFSTATUSPFRUNNING should be set after adfdev_init
ADFSTATUSPFRUNNING is (only) used and checked by adfvf2pfshutdown() before calling adfiovputmsg()->mutexlock(vf2pflock), however the vf2pflock is initialized in adfdevinit(), which can fail and when it fail, the vf2pflock is either not initialized or destroyed, a subsequent use of vf2pflock will cause issue. To fix this issue, only set this flag if adfdevinit() returns 0.
