Overview

CVE-2026-64039 is a high-severity vulnerability. It was published on July 19, 2026 and has a CVSS 3.1 base score of 7.7 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.7, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

drm/msm/snapshot: fix dumping of the unaligned regions

The snapshotting code internally aligns data segment to 16 bytes. This

works fine for DPU code (where most of the regions are aligned), but

fails for snapshotting of the DSI data (because DSI data region is

shifted by 4 bytes). Fix the code by removing length alignment and by

accurately printing last registers in the region. While reworking the

code also fix the 16x memory overallocation in

msm_disp_state_dump_regs().

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.
