CVE-2024-41022

Kernel memory corruption via unsigned SDMA instance index

Published Jul 29, 2024 · Updated Aug 5, 2026

Out-of-bounds access in affected Linux kernel releases allows local users to crash the system via malformed AMDGPU SDMA trap interrupts. sdma_v4_0_process_trap_irq stores a negative sdma_v4_0_irq_id_to_seq result in an unsigned instance variable, so its error check fails and amdgpu_fence_process indexes far beyond the SDMA instance array. Reachability requires local DRM render-node access and an unmapped client identifier from malformed hardware or firmware interrupt data; the resulting kernel memory corruption can panic the host.
