NVD Description

Note: Versions mentioned in the description apply only to the upstream bluez-libs-devel package and not the bluez-libs-devel package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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.
