Overview

CVE-2023-53378 is a high-severity vulnerability. It was published on September 18, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, 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:

drm/i915/dpt: Treat the DPT BO as a framebuffer

Currently i915_gem_object_is_framebuffer() doesn't treat the

BO containing the framebuffer's DPT as a framebuffer itself.

This means eg. that the shrinker can evict the DPT BO while

leaving the actual FB BO bound, when the DPT is allocated

from regular shmem.

That causes an immediate oops during hibernate as we

try to rewrite the PTEs inside the already evicted

DPT obj.

TODO: presumably this might also be the reason for the

DPT related display faults under heavy memory pressure,

but I'm still not sure how that would happen as the object

should be pinned by intel_dpt_pin() while in active use by

the display engine...

(cherry picked from commit 779cb5ba64ec7df80675a956c9022929514f517a)

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.
