GHSA-5FWG-75W6-7GF9
Vulnerability from github – Published: 2024-03-01 00:30 – Updated: 2025-01-09 21:31In 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.
