CVE-2024-41055

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

Description The issue is related to a NULL pointer dereference in the pfn section valid() function. This occurs due to a race condition with section deactivate() where ms->usage can be cleared. The addition of a READ ONCE() call around ms->usage is not sufficient to prevent the NULL pointer dereference, and a check of its value before dereferencing is necessary. There is no information provided about the estimated number of potentially affected devices or real-world incidents where this issue was exploited.

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