Overview

CVE-2025-37800 is a high-severity vulnerability. It was published on May 8, 2025 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

driver core: fix potential NULL pointer dereference in dev_uevent()

If userspace reads "uevent" device attribute at the same time as another

threads unbinds the device from its driver, change to dev->driver from a

valid pointer to NULL may result in crash. Fix this by using READ_ONCE()

when fetching the pointer, and take bus' drivers klist lock to make sure

driver instance will not disappear while we access it.

Use WRITE_ONCE() when setting the driver pointer to ensure there is no

tearing.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
