The code\ndeclared queue_priority_map as s8 (*)[2] (pointer to array of 2 s8),\nbut allocated memory using sizeof(s8) instead of the correct size.\n\nThis caused out-of-bounds memory writes when accessing:\n  queue_priority_map[i][0] = i;\n  queue_priority_map[i][1] = i;\n\nThe bug manifested as kernel crashes with \"Oops - undefined instruction\"\non ARM platforms (BeagleBoard-X15) during EDMA driver probe, as the\nmemory corruption triggered kernel hardening features on Clang.\n\nChange the allocation to use sizeof(*queue_priority_map) which\nautomatically gets the correct size for the 2D array structure.","modified":"2026-04-16T04:31:06.089441262Z","published":"2025-09-23T06:00:43.852Z","related":["SUSE-SU-2025:03600-1","SUSE-SU-2025:03614-1","SUSE-SU-2025:03615-1","SUSE-SU-2025:03628-1","SUSE-SU-2025:03634-1","SUSE-SU-2025:20851-1","SUSE-SU-2025:20861-1","SUSE-SU-2025:20870-1","SUSE-SU-2025:20898-1","SUSE-SU-2025:21074-1","SUSE-SU-2025:21139-1","SUSE-SU-2025:21179-1","SUSE-SU-2025:3716-1","SUSE-SU-2025:3751-1","SUSE-SU-2025:3761-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4141-1","openSUSE-SU-2025:20081-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/39xxx/CVE-2025-39869.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/069fd1688c57c0cc8a3de64d108579b31676f74b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1baed10553fc8b388351d8fc803e3ae6f1a863bc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/301a96cc4dc006c9a285913d301e681cfbf7edb6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5e462fa0dfdb52b3983cf41532d3d4c7d63e2f93"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7d4de60d6db02d9b01d5890d5156b04fad65d07a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d5e82f3f2c918d446df46e8d65f8083fd97cdec5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d722de80ce037dccf6931e778f4a46499d51bdf9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e63419dbf2ceb083c1651852209c7f048089ac0f"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00008.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/39xxx/CVE-2025-39869.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-39869"},{"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":"2b6b3b7420190888793c49e97276e1e73bd7eaed"},{"fixed":"7d4de60d6db02d9b01d5890d5156b04fad65d07a"},{"fixed":"d722de80ce037dccf6931e778f4a46499d51bdf9"},{"fixed":"301a96cc4dc006c9a285913d301e681cfbf7edb6"},{"fixed":"5e462fa0dfdb52b3983cf41532d3d4c7d63e2f93"},{"fixed":"1baed10553fc8b388351d8fc803e3ae6f1a863bc"},{"fixed":"069fd1688c57c0cc8a3de64d108579b31676f74b"},{"fixed":"d5e82f3f2c918d446df46e8d65f8083fd97cdec5"},{"fixed":"e63419dbf2ceb083c1651852209c7f048089ac0f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-39869.json"}}],"schema_version":"1.7.5"}
