{"id":"CVE-2021-47063","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm: bridge/panel: Cleanup connector on bridge detach\n\nIf we don't call drm_connector_cleanup() manually in\npanel_bridge_detach(), the connector will be cleaned up with the other\nDRM objects in the call to drm_mode_config_cleanup(). However, since our\ndrm_connector is devm-allocated, by the time drm_mode_config_cleanup()\nwill be called, our connector will be long gone. Therefore, the\nconnector must be cleaned up when the bridge is detached to avoid\nuse-after-free conditions.\n\nv2: Cleanup connector only if it was created\n\nv3: Add FIXME\n\nv4: (Use connector-\u003edev) directly in if() block","modified":"2026-03-15T22:42:47.412265Z","published":"2024-02-29T23:15:07.893Z","related":["SUSE-SU-2024:1454-1","SUSE-SU-2024:1465-1","SUSE-SU-2024:1489-1","SUSE-SU-2024:1643-1","SUSE-SU-2024:1646-1","SUSE-SU-2024:1870-1"],"references":[{"type":"FIX","url":"https://git.kernel.org/stable/c/18149b420c9bd93c443e8d1f48a063d71d9f6aa1"},{"type":"FIX","url":"https://git.kernel.org/stable/c/4d906839d321c2efbf3fed4bc31ffd9ff55b75c0"},{"type":"FIX","url":"https://git.kernel.org/stable/c/98d7d76a74e48ec3ddf2e23950adff7edcab9327"},{"type":"FIX","url":"https://git.kernel.org/stable/c/ce450934a00cf896e648fde08d0bd1426653d7a2"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"4.13"},{"fixed":"5.10.37"}]},{"events":[{"introduced":"5.11"},{"fixed":"5.11.21"}]},{"events":[{"introduced":"5.12"},{"fixed":"5.12.4"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-47063.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:H/I:H/A:H"}]}
