Vulnerability from github – Published: 2024-09-04 21:30 – Updated: 2025-03-07 18:31In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Fix deadlock during RTC update
There is a deadlock when runtime suspend waits for the flush of RTC work, and the RTC work calls ufshcd_rpm_get_sync() to wait for runtime resume.
Here is deadlock backtrace:
