Integer overflow in Linux kernel - CVE-2026-74417

Vulnerability identifier: #VU142710

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-74417

CWE-ID: CWE-190

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to integer overflow in radeon_align_pitch() when creating a dumb buffer. A local user can supply crafted width or bits-per-pixel values to cause a denial of service.

The issue can result in an invalid pitch or a zero-sized dumb buffer.
