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."}],"affected":[{"vendor":"bluez","product":"bluez","versions":[{"version":"= 5.58","status":"affected"}]}],"references":[{"url":"https://github.com/bluez/bluez/security/advisories/GHSA-3fqg-r8j5-f5xq"},{"name":"[debian-lts-announce] 20211127 [SECURITY] [DLA 2827-1] bluez security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2021/11/msg00022.html"},{"url":"https://security.netapp.com/advisory/ntap-20211203-0004/"},{"name":"[debian-lts-announce] 20221024 [SECURITY] [DLA 3157-1] bluez security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2022/10/msg00026.html"}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW","baseScore":4.3,"baseSeverity":"MEDIUM"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-400: Uncontrolled Resource Consumption","cweId":"CWE-400"}]}],"source":{"advisory":"GHSA-3fqg-r8j5-f5xq","discovery":"UNKNOWN"}},"adp":[{"title":"CVE Program Container","references":[{"url":"https://github.com/bluez/bluez/security/advisories/GHSA-3fqg-r8j5-f5xq","tags":["x_transferred"]},{"name":"[debian-lts-announce] 20211127 [SECURITY] [DLA 2827-1] bluez security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2021/11/msg00022.html"},{"url":"https://security.netapp.com/advisory/ntap-20211203-0004/","tags":["x_transferred"]},{"name":"[debian-lts-announce] 20221024 [SECURITY] [DLA 3157-1] bluez security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2022/10/msg00026.html"},{"url":"https://lists.debian.org/debian-lts-announce/2024/09/msg00022.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-04T16:09:18.907Z"}}]}}
