# CVE-2024-44953

> 3.1 LOW

## Beschreibung

In 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:
