Overview

CVE-2026-53330 is a high-severity vulnerability. It was published on July 1, 2026 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, 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: Fix out-of-bounds read in dp_get_eq_aux_rd_interval()

[Why & How]

The aux_rd_interval array in struct dc_lttpr_caps is declared with

MAX_REPEATER_CNT - 1 (7) elements, indexed 0..6. However, the offset

parameter passed to dp_get_eq_aux_rd_interval() can be as large as

MAX_REPEATER_CNT (8) when a sink reports 8 LTTPR repeaters via DPCD.

This leads to an out-of-bounds read of aux_rd_interval[7] when offset

is 8.

Fix this by growing aux_rd_interval to MAX_REPEATER_CNT elements to

accommodate the full range of valid repeater counts defined by the DP

spec.

(cherry picked from commit a55a458a8df37a65ffda5cf721d554a8f74f6b04)

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.
