{"id":"CVE-2026-53201","summary":"Revert \"drm/xe: Skip exec queue schedule toggle if queue is idle during suspend\"","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRevert \"drm/xe: Skip exec queue schedule toggle if queue is idle during suspend\"\n\nThis reverts commit 8533051ce92015e9cc6f75e0d52119b9d91610b6.\n\nThe idle-skip optimization bypasses GuC suspend, so the GPU may not\nperform the context switch that flushes TLB entries for invalidated\nuserptr VMAs. In LR/preempt-fence VM mode, this can lead to missed TLB\ninvalidation and page faults during userptr invalidation tests.\n\nRestore unconditional schedule toggling on suspend so the context-switch\nTLB flush is always performed.\n\nThis optimization will be reintroduced with a fix that does not skip\nsuspend in LR/preempt-fence VM mode.\n\n(cherry picked from commit 6a1e7934d9a6cf46aecae00a99c2603d1295e170)","modified":"2026-08-12T03:51:13.560754171Z","published":"2026-06-25T08:39:09.631Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53201.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/b69b715f48ac7e802c89ed5924795c5b055da91e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fa7c84726dc217ce0c183926ef9411636c7a2213"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53201.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53201"},{"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":"8533051ce92015e9cc6f75e0d52119b9d91610b6"},{"fixed":"b69b715f48ac7e802c89ed5924795c5b055da91e"},{"fixed":"fa7c84726dc217ce0c183926ef9411636c7a2213"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53201.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.0.13"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53201.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
