Vulnerability from github – Published: 2025-03-06 18:31 – Updated: 2025-11-02 15:30

Details

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

iommu/vt-d: Avoid use of NULL after WARN_ON_ONCE

There is a WARN_ON_ONCE to catch an unlikely situation when domain_remove_dev_pasid can't find the pasid. In case it nevertheless happens we must avoid using a NULL pointer.

Severity

5.5 (Medium)
