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.","severity":{"version":"3.1","score":4.3,"vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.01184,"percentile":0.68018,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-400","CWE-401"],"published":"2021-11-12T00:00:00Z","modified":"2026-10-29T11:01:06Z","fixes":[{"ecosystem":"AlmaLinux:8","package":"bluez","fixed_in":["5.56-3.el8"],"sources":["osv"]},{"ecosystem":"AlmaLinux:8","package":"bluez-cups","fixed_in":["5.56-3.el8"],"sources":["osv"]},{"ecosystem":"AlmaLinux:8","package":"bluez-hid2hci","fixed_in":["5.56-3.el8"],"sources":["osv"]},{"ecosystem":"AlmaLinux:8","package":"bluez-libs","fixed_in":["5.56-3.el8"],"sources":["osv"]},{"ecosystem":"AlmaLinux:8","package":"bluez-libs-devel","fixed_in":["5.56-3.el8"],"sources":["osv"]},{"ecosystem":"AlmaLinux:8","package":"bluez-obexd","fixed_in":["5.56-3.el8"],"sources":["osv"]},{"ecosystem":"Debian:12","package":"bluez","fixed_in":["5.62-2"],"sources":["osv"]},{"ecosystem":"Debian:13","package":"bluez","fixed_in":["5.62-2"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"bluez","fixed_in":["5.62-2"],"sources":["osv"]},{"ecosystem":"openEuler:20.03-LTS-SP1","package":"bluez","fixed_in":["5.54-10.oe1"],"sources":["osv"]},{"ecosystem":"openEuler:20.03-LTS-SP3","package":"bluez","fixed_in":["5.54-10.oe1"],"sources":["osv"]},{"ecosystem":"openEuler:22.03-LTS","package":"bluez","fixed_in":["5.54-14.oe2203"],"sources":["osv"]},{"ecosystem":"Red
