{"id":"CVE-2026-68259","summary":"drm/amdkfd: Check bounds in allocate_event_notification_slot","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdkfd: Check bounds in allocate_event_notification_slot\n\nThe valid event ids go from 0 to KFD_SIGNAL_EVENT_LIMIT\n\nallocate_event_notification_slot has an option to specify\nan event id to allocate at, used by CRIU. We weren't checking\nthe bounds on that value.\n\nCheck them.\n\nv2: Lower bounds check is unecessary because of idr_alloc\nalready rejecting negative numbers. Upper bounds check should\nbe KFD_SIGNAL_EVENT_LIMIT since the signal mode mappings might\nnot yet exist\n\n(cherry picked from commit 6853f1f6cbbeb3f53ebbbd7286536aeb2c5d5f50)","modified":"2026-08-21T03:30:31.541872773Z","published":"2026-08-10T12:01:33.110Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68259.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4622214f0542f64b02c250db0f9c677eeb032d9b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/50319efb865f72db45f191c8709511746d58ee0a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6884fc142b17f456caac50c14505f509bfbcd012"},{"type":"WEB","url":"https://git.kernel.org/stable/c/85eedff5f0c4aba5a66bc37a1bd6bcecd0d77b53"},{"type":"WEB","url":"https://git.kernel.org/stable/c/abeeb1947d81610c65349db4d89c6151f270e136"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bb52249fbbe948875155ccd45cd8d74bf4ae747b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68259.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68259"},{"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":"40e8a766a761f7fdc8530347527b344fddf6f1a8"},{"fixed":"6884fc142b17f456caac50c14505f509bfbcd012"},{"fixed":"85eedff5f0c4aba5a66bc37a1bd6bcecd0d77b53"},{"fixed":"4622214f0542f64b02c250db0f9c677eeb032d9b"},{"fixed":"50319efb865f72db45f191c8709511746d58ee0a"},{"fixed":"abeeb1947d81610c65349db4d89c6151f270e136"},{"fixed":"bb52249fbbe948875155ccd45cd8d74bf4ae747b"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68259.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.18.0"},{"fixed":"6.1.183"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68259.json"}}],"schema_version":"1.9.0"}
