A paired Bluetooth device acting as a PBAP server can overflow the heap in obexd by up to 239 bytes into adjacent allocations by returning a DATABASEID_TAG application parameter with an oversized length. With both length and content fully attacker-controlled, this enables standard glibc heap exploitation primitives (tcache/fastbin poisoning) leading to remote code execution in the obexd process.
