Medium (4.7) in linux linux kernel. EPSS 0.2% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Fix racing issue between ufshcd_mcq_abort() and ISR
If command timeout happens and cq complete IRQ is raised at the same time,

ISR. Error log:
ufshcd_abort: Device abort task at tag 18
Unable to handle kernel NULL pointer dereference at virtual address
