CVSS v4.0

5.7

Medium

VectorAV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.12.0-rc3
Description A potential deadlock issue has been identified in the Linux kernel's f2fs subsystem. The issue arises from a possible circular locking dependency detected in the f2fs record stop reason() function. This can occur when the kswapd0 task attempts to acquire a lock while already holding another lock, which can lead to a deadlock situation. The estimated number of potentially affected devices worldwide is not specified.
Recommendations To resolve this issue, update the Linux kernel to a version that includes the fix for the potential deadlock in f2fs record stop reason(). As a temporary workaround, consider disabling the f2fs record stop reason() function until a patch is available. However, this may have unintended consequences and should be approached with caution.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
