Overview

CVE-2026-93180 is a known-severity vulnerability. It was published on September 17, 2026.

Technical description

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

drm/panthor: Fix NPD issue on partial unmap of an evicted BO

This commit fixes the NULL pointer dereference issue that would have

happened on the split of GPU mapping due to partial unmap of an evicted

BO. There is a logic to handle the partial unmap of huge pages when the

GPU mapping is split. That logic was not being completely skipped for

the VMA of an evicted BO and that resulted in a NPD possibility for the

'bo->backing.pages' pointer, which is set to NULL when pages of a

BO are released on eviction.

Following dump was seen when a partial unmap was exercised for an

evicted BO.

How can CyberStrike help with CVE-2026-93180?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-93180 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
