{"id":"CVE-2026-90064","summary":"drm/xe: Reject page faults from non-fault-mode scratch VMs","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe: Reject page faults from non-fault-mode scratch VMs\n\nHaving scratch enabled does not make a VM capable of handling recoverable\npage faults. Allowing scratch VMs through the ASID lookup also admits\ndma-fence mode VMs.\n\nIf such a VM faults on an already valid VMA, the handler reports success\nwithout fixing the fault, causing the GPU to retry indefinitely.\n\nOnly allow fault-mode VMs through the ASID lookup. Fault-mode VMs using\nscratch remain supported, while faults from 3D VMs are rejected.\n\n(cherry picked from commit bfb24a06405b652d37831f3fb66b71d33a6605de)","modified":"2026-09-19T03:47:24.049802760Z","published":"2026-09-17T16:05:47.607Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90064.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5e977521d21717edb8e91d004434697d6e3f248c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/905d648e97ef3a291f71a935a7fab0133f27f0f7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90064.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90064"},{"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":"ad9843aac91a1eda12912a4922042ea04cfc29dc"},{"fixed":"905d648e97ef3a291f71a935a7fab0133f27f0f7"},{"fixed":"5e977521d21717edb8e91d004434697d6e3f248c"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90064.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.1.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90064.json"}}],"schema_version":"1.9.0"}
