    "data": "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. BlueZ Contains a vulnerability regarding the lack of free memory after expiration.Service operation interruption (DoS) It may be in a state. \n\r\n\r\nBlueZ has a resource management error vulnerability. The vulnerability stems from a vulnerability in the cstate alloc buf of the sdp in the affected version. ==========================================================================\nUbuntu Security Notice USN-5155-1\nNovember 23, 2021\n\nbluez vulnerabilities\n==========================================================================\n\nA security issue affects these releases of Ubuntu and its derivatives:\n\n- Ubuntu 21.10\n- Ubuntu 21.04\n- Ubuntu 20.04 LTS\n- Ubuntu 18.04 LTS\n\nSummary:\n\nSeveral security issues were fixed in BlueZ. \n\nSoftware Description:\n- bluez: Bluetooth tools and daemons\n\nDetails:\n\nIt was discovered that BlueZ incorrectly handled the Discoverable status\nwhen a device is powered down.
