CVE-2026-74417: drm/radeon: fix integer overflow in radeon_align_pitch()

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 415bb9893e249e46aa5159f7363a11512cf06fa9, 9e0c822907bedeaec317f84e6990d265f03db85d, b7b44937c548c2c987fcdd129f8896741004bed6.

Low priority for now. Upgrade to Linux Linux 415bb9893e249e46aa5159f7363a11512cf06fa9, 9e0c822907bedeaec317f84e6990d265f03db85d, b7b44937c548c2c987fcdd129f8896741004bed6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
