Overview

CVE-2026-53329 is a high-severity vulnerability. It was published on July 1, 2026 and has a CVSS 3.1 base score of 7.0 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.0, 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/amd/display: Use krealloc_array() in dal_vector_reserve()

[Why & How]

dal_vector_reserve() computes the allocation size as

"capacity * vector->struct_size" using uint32_t arithmetic, which can

silently wrap to a small value on overflow. This would cause krealloc to

return a smaller buffer than expected, leading to heap overflows on

subsequent vector appends.

Replace krealloc() with krealloc_array() which performs an internal

overflow check and returns NULL on wrap, preventing the issue.

(cherry picked from commit 37668568641ccc4cc1dbca4923d0a16609dd5707)

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.
