{"id":"CVE-2023-53002","summary":"drm/i915: Fix a memory leak with reused mmap_offset","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/i915: Fix a memory leak with reused mmap_offset\n\ndrm_vma_node_allow() and drm_vma_node_revoke() should be called in\nbalanced pairs. We call drm_vma_node_allow() once per-file everytime a\nuser calls mmap_offset, but only call drm_vma_node_revoke once per-file\non each mmap_offset. As the mmap_offset is reused by the client, the\nper-file vm_count may remain non-zero and the rbtree leaked.\n\nCall drm_vma_node_allow_once() instead to prevent that memory leak.","modified":"2026-04-02T09:43:32.263808Z","published":"2025-03-27T16:43:34.479Z","related":["SUSE-SU-2025:01620-1","SUSE-SU-2025:01640-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53002.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0220e4fe178c3390eb0291cdb34912d66972db8a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0bdc4b4ba7206c452ee81c82fa66e39d0e1780fb"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53002.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53002"},{"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":"7865559872074a9ab169c87915504661d630addf"},{"fixed":"0bdc4b4ba7206c452ee81c82fa66e39d0e1780fb"},{"fixed":"0220e4fe178c3390eb0291cdb34912d66972db8a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53002.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
