Description OSIDB Bzimport 2025-09-15 13:01:36 UTC 
In the Linux kernel, the following vulnerability has been resolved:

scsi: ufs: core: Remove WARN_ON_ONCE() call from ufshcd_uic_cmd_compl()

The UIC completion interrupt may be disabled while an UIC command is
being processed. When the UIC completion interrupt is reenabled, an UIC
interrupt is triggered and the WARN_ON_ONCE(!cmd) statement is hit.
Hence this patch that removes this kernel warning.
