{"id":"CVE-2021-47360","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbinder: make sure fd closes complete\n\nDuring BC_FREE_BUFFER processing, the BINDER_TYPE_FDA object\ncleanup may close 1 or more fds. The close operations are\ncompleted using the task work mechanism -- which means the thread\nneeds to return to userspace or the file object may never be\ndereferenced -- which can lead to hung processes.\n\nForce the binder thread back to userspace if an fd is closed during\nBC_FREE_BUFFER handling.","modified":"2026-03-14T14:59:08.977568Z","published":"2024-05-21T15:15:22.210Z","related":["SUSE-SU-2024:2008-1","SUSE-SU-2024:2011-1","SUSE-SU-2024:2019-1","SUSE-SU-2024:2189-1","SUSE-SU-2024:2190-1"],"references":[{"type":"FIX","url":"https://git.kernel.org/stable/c/5fdb55c1ac9585eb23bb2541d5819224429e103d"},{"type":"FIX","url":"https://git.kernel.org/stable/c/aa2c274c279ff365a06a4cba263f04965895166e"},{"type":"FIX","url":"https://git.kernel.org/stable/c/b95483d8d94b41fa31a84c1d86710b7907a37621"},{"type":"FIX","url":"https://git.kernel.org/stable/c/d5b0473707fa53b03a5db0256ce62b2874bddbc7"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-47360.json","unresolved_ranges":[{"events":[{"introduced":"5.0"},{"fixed":"5.4.150"}]},{"events":[{"introduced":"5.5"},{"fixed":"5.10.70"}]},{"events":[{"introduced":"5.11"},{"fixed":"5.14.9"}]},{"events":[{"introduced":"0"},{"last_affected":"4.20.1"}]},{"events":[{"introduced":"0"},{"last_affected":"5.15-rc1"}]},{"events":[{"introduced":"0"},{"last_affected":"5.15-rc2"}]}]}}],"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"}]}
