An issue was discovered in bluetoothd in BlueZ through 5.48. The vulnerability lies in the handling of a SVC_ATTR_REQ by the SDP implementation. By crafting a malicious CSTATE, it is possible to trick the server into returning more bytes than the buffer actually holds, resulting in leaking arbitrary heap data. The root cause can be found in the function service_attr_req of sdpd-request.c. The server does not check whether the CSTATE data is the same in consecutive requests, and instead simply trusts that it is the same.

As per you note this was vulnerable "through 5.48". We build 5.49 for Fedora 27/28/29 on Mar 20 2018, this CVE has been fixed for nearly 4 years in Fedora why is this being opened now?
Actually it looks like el8 is 5.56-2.el8 so it looks like this is fixed in RHEL-8 too

Hi, this is a flaw bug and it's used to track all Red Hat products that may be affected by this issue, it's not just for Fedora.
