CVE-2025-37800

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

Description A potential NULL pointer dereference in the dev uevent() function has been resolved. This issue occurs when userspace reads the "uevent" device attribute at the same time as another thread unbinds the device from its driver, causing a crash. The fix involves using READ ONCE() when fetching the pointer and taking the bus' drivers klist lock to prevent the driver instance from disappearing while accessing it. Additionally, WRITE ONCE() is used when setting the driver pointer to ensure there is no tearing.

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