CVE-2026-74416: drm/radeon: fix memory leak in radeon_ring_restore() on lock failure

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.22% (FIRST EPSS).
  • Fixed version: Linux Linux 06dc892561f5a08b2493c34c8ec2cb94dea33159, 07c213f3499dd72e2922c1c73fe9ffea24874bef, 1c9ba32308c02c198c378fcdf06be9ffc3111147.

Low priority for now. Upgrade to Linux Linux 06dc892561f5a08b2493c34c8ec2cb94dea33159, 07c213f3499dd72e2922c1c73fe9ffea24874bef, 1c9ba32308c02c198c378fcdf06be9ffc3111147 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: fix memory leak in radeon_ring_restore() on lock failure radeon_ring_restore() takes ownership of the data buffer allocated by radeon_ring_backup(). The caller (radeon_gpu_reset()) only frees it in the non-restore branch; in the restore branch it relies on radeon_ring_restore() to free it. If radeon_ring_lock() fails, the function returned early without calling kvfree(data), leaking the ring backup buffer on every GPU reset that fails at the lock stage. During repeated GPU resets this causes cumulative kernel memory exhaustion. Free data before returning the error.
