Detailed vulnerability description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to a race condition in ufshcd_rtc_work() and the UFS suspend path when suspending UFS devices. A local user can trigger UFS suspend while the delayed RTC work is still running to cause a denial of service.
The issue can trigger an asynchronous SError that leads to a kernel panic on affected systems.
