Overview

CVE-2026-74417 is a high-severity vulnerability. It was published on August 15, 2026 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/radeon: fix integer overflow in radeon_align_pitch()

radeon_align_pitch() has the same kind of overflow issue as the old

amdgpu helper: both the alignment round-up add and the final

'aligned * cpp' calculation can overflow signed int.

If that wraps, radeon_mode_dumb_create() can end up returning an

invalid pitch or creating a zero-sized dumb buffer.

Fix this by using check_add_overflow() for the alignment round-up and

check_mul_overflow() for the final pitch calculation, returning 0 on

overflow. Also reject zero pitch and size in

radeon_mode_dumb_create().

Found via AST-based call-graph analysis using sqry.

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.
