{"id":"CVE-2026-23350","summary":"drm/xe/queue: Call fini on exec queue creation fail","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe/queue: Call fini on exec queue creation fail\n\nEvery call to queue init should have a corresponding fini call.\nSkipping this would mean skipping removal of the queue from GuC list\n(which is part of guc_id allocation). A damaged queue stored in\nexec_queue_lookup list would lead to invalid memory reference,\nsooner or later.\n\nCall fini to free guc_id. This must be done before any internal\nLRCs are freed.\n\nSince the finalization with this extra call became very similar to\n__xe_exec_queue_fini(), reuse that. To make this reuse possible,\nalter xe_lrc_put() so it can survive NULL parameters, like other\nsimilar functions.\n\nv2: Reuse _xe_exec_queue_fini(). Make xe_lrc_put() aware of NULLs.\n\n(cherry picked from commit 393e5fea6f7d7054abc2c3d97a4cfe8306cd6079)","modified":"2026-04-02T13:12:22.709113Z","published":"2026-03-25T10:27:36.182Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23350.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/99f9b5343cae80eb0dfe050baf6c86d722b3ba2e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fae65b8a4449ae556990efcde8d74bec4adc5925"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23350.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23350"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"3c1fa4aa60b146d1fa73b2b87064303f8e4b7952"},{"fixed":"fae65b8a4449ae556990efcde8d74bec4adc5925"},{"fixed":"99f9b5343cae80eb0dfe050baf6c86d722b3ba2e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23350.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23350.json"}}],"schema_version":"1.7.5"}
