{"id":"CVE-2021-41229","details":"BlueZ is a Bluetooth protocol stack for Linux. In affected versions a vulnerability exists in sdp_cstate_alloc_buf which allocates memory which will always be hung in the singly linked list of cstates and will not be freed. This will cause a memory leak over time. The data can be a very large object, which can be caused by an attacker continuously sending sdp packets and this may cause the service of the target device to crash.","aliases":["GHSA-3fqg-r8j5-f5xq"],"modified":"2026-07-07T08:50:55.798944638Z","published":"2021-11-12T23:15:08.857Z","related":["ALSA-2022:2081","SUSE-SU-2023:3238-1","SUSE-SU-2023:3240-1","SUSE-SU-2023:3689-1","SUSE-SU-2024:0166-1","SUSE-SU-2024:0167-1"],"database_specific":{"unresolved_ranges":[{"source":"CPE_STRING","vendor_product":"debian:debian_linux","cpes":["cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"9.0"},{"last_affected":"9.0"},{"introduced":"10.0"},{"last_affected":"10.0"}]}]},"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/09/msg00022.html"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2021/11/msg00022.html"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2022/10/msg00026.html"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20211203-0004/"},{"type":"EVIDENCE","url":"https://github.com/bluez/bluez/security/advisories/GHSA-3fqg-r8j5-f5xq"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/bluez/bluez","events":[{"introduced":"2e4397acbb75d83a75d11769f69cb12211cd9045"},{"last_affected":"2e4397acbb75d83a75d11769f69cb12211cd9045"}],"database_specific":{"cpe":"cpe:2.3:a:bluez:bluez:5.58:*:*:*:*:*:*:*","extracted_events":[{"introduced":"5.58"},{"last_affected":"5.58"}],"source":"CPE_STRING"}}],"versions":["5.58"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2021-41229.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
