NULL Pointer Dereference Affecting kernel-64k-devel-matched package, versions *
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

In 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.
