  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu: force complete the KIQ ring fences on reset\n\nLike the MES scheduler ring, the KIQ ring sets no_scheduler = true and uses a\npolling fence, so it is skipped by the force-completion loop in\namdgpu_device_pre_asic_reset(). Its hw fence value lives in wb (GTT) memory and\nsurvives a MODE1 reset while fence_drv.sync_seq keeps advancing, so after a\nreset the first KIQ submission can poll forever on a seq that is never written\nback.\n\nForce complete the KIQ ring fences too so their hw fence is realigned to\nsync_seq.",
