This CVE record has recently been published to the CVE List and has been included within the NVD dataset. DescriptionIn the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Fix possible NULL pointer dereference in ufshcd_add_command_trace() The kernel log indicates a crash in ufshcd_add_command_trace, due to a NULL pointer dereference when accessing hwq->id. This can happen if ufshcd_mcq_req_to_hwq() returns NULL. This patch adds a NULL check for hwq before accessing its id field to prevent a kernel crash.
