{"id":"CVE-2026-89813","summary":"drm/amdgpu: force complete the KIQ ring fences on reset","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.","modified":"2026-09-18T03:48:32.977885424Z","published":"2026-09-16T10:30:46.201Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89813.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/bdd6a58743e00ebc6d52b9cdf9aafb4e535e0b71"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fd65d1742992361fc2201ecb4e43411e6e417fcb"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89813.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89813"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"65781c78ad74e4260fbec92c0ecc05738044e177"},{"fixed":"bdd6a58743e00ebc6d52b9cdf9aafb4e535e0b71"},{"fixed":"fd65d1742992361fc2201ecb4e43411e6e417fcb"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89813.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.13.0"},{"fixed":"7.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89813.json"}}],"schema_version":"1.9.0"}
