What is CVE-2026-80185?

A type confusion vulnerability has been identified in the BlueZ Bluetooth daemon, specifically in the handling of ServiceRecord registration within the SDP XML parser. This flaw allows for a crafted nested ServiceRecord to disrupt the stack of the SDP XML parser, causing it to misinterpret scalar union data as a sequence pointer. As a result, a local attacker could potentially exploit this weakness to crash the bluetoothd service, leading to a denial of service situation.
