Description
CVE-2026-74417 is a high-severity vulnerability in the Linux kernel's drm/radeon component. It involves an integer overflow in the radeon_align_pitch() function, which can cause invalid pitch values or zero-sized dumb buffers to be created. The issue arises from overflow in alignment rounding and pitch calculation using signed integers. The vulnerability has been fixed by adding overflow checks and rejecting zero pitch and size in the affected function.
