{"id":"CVE-2023-53552","summary":"drm/i915: mark requests for GuC virtual engines to avoid use-after-free","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/i915: mark requests for GuC virtual engines to avoid use-after-free\n\nReferences to i915_requests may be trapped by userspace inside a\nsync_file or dmabuf (dma-resv) and held indefinitely across different\nproceses. To counter-act the memory leaks, we try to not to keep\nreferences from the request past their completion.\nOn the other side on fence release we need to know if rq-\u003eengine\nis valid and points to hw engine (true for non-virtual requests).\nTo make it possible extra bit has been added to rq-\u003eexecution_mask,\nfor marking virtual engines.\n\n(cherry picked from commit 280410677af763f3871b93e794a199cfcf6fb580)","modified":"2026-04-02T09:44:26.457202Z","published":"2025-10-04T15:16:58.429Z","related":["ALSA-2026:0759","ALSA-2026:0760","SUSE-SU-2025:21040-1","SUSE-SU-2025:21052-1","SUSE-SU-2025:21056-1","SUSE-SU-2025:21064-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4111-1","SUSE-SU-2025:4128-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4139-1","SUSE-SU-2025:4140-1","SUSE-SU-2025:4141-1","SUSE-SU-2025:4149-1","SUSE-SU-2025:4301-1","SUSE-SU-2025:4320-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53552.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5eefc5307c983b59344a4cb89009819f580c84fa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7fb464d52fa41c31a6fd1ad82888e67c65935d94"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8017a27cec32eac8c8f9430b0a3055840136b856"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53552.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53552"},{"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":"bcb9aa45d5a0e11ef91245330c53cde214d15e8d"},{"fixed":"8017a27cec32eac8c8f9430b0a3055840136b856"},{"fixed":"7fb464d52fa41c31a6fd1ad82888e67c65935d94"},{"fixed":"5eefc5307c983b59344a4cb89009819f580c84fa"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53552.json"}}],"schema_version":"1.7.5"}
