Summary
In the Linux kernel, the following vulnerability has been resolved: crypto: qat - ADF_STATUS_PF_RUNNING should be set after adf_dev_init ADF_STATUS_PF_RUNNING is (only) used and checked by adf_vf2pf_shutdown() before calling adf_iov_putmsg()->mutex_lock(vf2pf_lock), however the vf2pf_lock is initialized in adf_dev_init(), which can fail and when it fail, the vf2pf_lock is either not initialized or destroyed, a subsequent use of vf2pf_lock will cause issue. To fix this issue, only set this flag if adf_dev_init() returns 0. [ 7.178404] BUG: KASAN: user-memory-access in __mutex_lock.isra.0+0x1ac/0x7c0 [ 7.180345] Call Trace: [ 7.182576] mutex_lock+0xc9/0xd0 [ 7.183257] adf_iov_putmsg+0x118/0x1a0 [intel_qat] [ 7.183541] adf_vf2pf_shutdown+0x4d/0x7b [intel_qat] [ 7.183834] adf_dev_shutdown+0x172/0x2b0 [intel_qat] [ 7.184127] adf_probe+0x5e9/0x600 [qat_dh895xccvf]
