CVE-2024-46725

Kernel memory corruption via unchecked ring type

Published Sep 18, 2024 · Updated Aug 5, 2026

An out-of-bounds write in the Linux kernel amdgpu driver allows local users to corrupt kernel memory through DRM ioctls. During ring registration, amdgpu_ring_init indexes gpu_sched with an unchecked ring type, then uses an out-of-bounds num_scheds value to write a scheduler pointer beyond the table. Reachability requires an affected kernel with an AMD GPU using amdgpu; an unprivileged render-node user can cause kernel-memory disclosure, control-flow corruption, or a kernel oops and wedged system.
