CVE-2026-80185
Bluez: sdp-xml: bluez 5.86: unprivileged-local and adjacent-le-peer leads to arbitrary code execution as root
BlueZ sdp-xml.c type confusion via RegisterProfile(ServiceRecord) can crash bluetoothd (local DoS): a crafted nested ServiceRecord can corrupt the SDP XML parser stack so scalar union data is treated as a sequence pointer, allowing a local caller to crash bluetoothd.
Fixes and workarounds
Workaround
Until a fix is available, restrict untrusted local access to the org.bluez.ProfileManager1.RegisterProfile D-Bus method, or more broadly to the org.bluez name on the system bus, for example via a D-Bus system bus policy or polkit rule, so that untrusted callers cannot submit arbitrary ServiceRecord XML. Disabling the Bluetooth service on systems where it is not required also reduces exposure.
