Description OSIDB Bzimport 2026-09-17 17:47:34 UTC 
In the Linux kernel, the following vulnerability has been resolved:

scsi: ufs: Avoid NULL CQE dereference when reporting invalid tags

The single-doorbell completion path can call ufshcd_compl_one_cqe() with a
NULL CQE. If no command is associated with the completion tag, the warning
message dereferences the CQE while reporting the error.  Avoid that
dereference and include the invalid tag in the warning.
