Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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 Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Recommended fix Moderate confidence

Linux kernel version containing the radeon_align_pitch() overflow fix (check kernel.org/git or distribution security advisories for the specific version)

  1. Identify the current Linux kernel version running on the system (e.g., `uname -r`)
  2. Check the distribution's security advisories or the Linux kernel changelog for CVE-2026-74417
  3. Upgrade the Linux kernel to the version that includes the fix for the integer overflow in radeon_align_pitch()
  4. Reboot the system to load the new kernel
  5. Verify the fix is applied by checking the kernel version and ensuring the radeon driver loads without errors (e.g., `dmesg | grep -i radeon`)
Caveat Kernel upgrades may introduce compatibility changes; ensure dependent modules and drivers are compatible with the new kernel version
