CVE-2023-53378 Vulnerability Summary

CVE-2023-53378: 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)

Assessing the Risk of CVE-2023-53378

Access Complexity Graph

The exploitability of CVE-2023-53378 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2023-53378

No exploitability data is available for CVE-2023-53378.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2023-53378, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
