CVE-2024-39501

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

Description: The issue is related to a race condition in the Linux kernel, specifically between the really probe() and dev uevent() functions. This race condition can occur when these functions run in different threads, leading to a potential system crash. The problem arises when dev->driver is set to NULL in really probe() and then accessed in dev uevent() after the check, causing the system to crash. The fix involves adding a lock to the non-protected path to prevent this race condition. Similar cases have been reported by syzkaller, but they are considered false-positives as they relate to the initialization of dev->driver. The same issue was previously reported and attempted to be fixed in 2015.

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