CVE-2026-64151

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

Description An issue exists in the iommupt component where the driver could omit PAGE SIZE from the pgsize bitmap. While technically permitted, this behavior contradicts the intended design. The fix involves adjusting the PT WARN ON logic to skip the fast path when this condition occurs.

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