CVE-2024-26657

CVE-2024-26657 relates to a NULL pointer dereference in the Linux kernel’s DRM scheduler code (drm_sched_entity_init). The issue could be triggered by AMDGPU user-space IOCTL flow: user calls AMDGPU_CTX_ALLOC_CTX via amdgpu_ctx_ioctl, then AMDGPU_WAIT_CS without submitting a job, which could lead...
