Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A race condition exists in the ufshcd wl suspend() function. The cancel delayed work sync() call is positioned after ufshcd vops suspend(), allowing ufshcd rtc work() to run while ufshcd vops suspend() is executing. When UFSHCD CAP CLK GATING is not supported, ufshcd update rtc() is executed. Because ufshcd vops suspend() typically performs clock gating operations, this sequence triggers an SError (Asynchronous SError Interrupt), leading to a kernel panic.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
