{"id":"CVE-2026-46224","summary":"drm/xe: Fix bo leak in xe_dma_buf_init_obj() on allocation failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe: Fix bo leak in xe_dma_buf_init_obj() on allocation failure\n\nWhen drm_gpuvm_resv_object_alloc() fails, the pre-allocated storage bo\nis not freed. Add xe_bo_free(storage) before returning the error.\n\nxe_dma_buf_init_obj() calls xe_bo_init_locked(), which frees the bo on\nerror. Therefore, xe_dma_buf_init_obj() must also free the bo on its own\nerror paths. Otherwise, since xe_gem_prime_import() cannot distinguish\nwhether the failure originated from xe_dma_buf_init_obj() or from\nxe_bo_init_locked(), it cannot safely decide whether the bo should be\nfreed.\n\nAdd comments documenting the ownership semantics: on success, ownership\nof storage is transferred to the returned drm_gem_object; on failure,\nstorage is freed before returning.\n\nv2: Add comments to explain the free logic.\n\n(cherry picked from commit 78a6c5f899f22338bbf48b44fb8950409c5a69b9)","modified":"2026-07-08T08:02:18.050771224Z","published":"2026-05-28T09:40:42.819Z","related":["openSUSE-SU-2026:10954-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46224.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/8fa8c2a22585fcb31dc605b91a67bbcca223fdd7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/93a528f67ce5095bcab46a69839eca97f43dd352"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f9ad21b90162baf1d78f8036ff3813c3ec1ac88e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46224.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46224"},{"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":"eb289a5f6cc668853f9b2ea6aca04afe58ed11c7"},{"fixed":"f9ad21b90162baf1d78f8036ff3813c3ec1ac88e"},{"fixed":"8fa8c2a22585fcb31dc605b91a67bbcca223fdd7"},{"fixed":"93a528f67ce5095bcab46a69839eca97f43dd352"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46224.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.18.0"},{"fixed":"6.18.32"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46224.json"}}],"schema_version":"1.7.5"}
