Hello all o/ This is intentional. And easy to reverse.
The patch for CVE-2023-45866 works as intended and is not a regression. https://git.kernel.org/pub/scm/bluetooth/bluez.git/commit/profiles/input?id=25a471a83e02e1effb15d5a488b3f0085eaeb675 If ClassicBondedOnly is not enforced, a nearby attacker can create a HID (like a keyboard and mouse) on the victims PC when bluetooth is discoverable. An HID can be used as a keyloggers or, of course, give direct control of the session. The CVE reporter has discussed this further on https://github.com/skysafe/reblog/tree/main/cve-2023-45866 And a talk and PoC release is forthcoming. Fortunately, it is easy to enable legacy devices by setting `ClassicBondedOnly=false` in `/etc/bluetooth/input.conf`, and then running `systemctl restart bluetooth`. I ver ified that a PS3 controller works well after this :) All other distros *should* be fixing this CVE. I would love it if bloggers in the Linux gaming sphere could raise awareness about this CVE and share how to enable legacy bluetooth device support. ** CVE added: https://cve.mitre.org/cgi-bin/cvename.cgi?name=2023-45866 ** Changed in: bluez (Ubuntu) Status: Confirmed => Won't Fix ** Changed in: bluez (Ubuntu) Assignee: Nishit Majithia (0xnishit) => Mark Esler (eslerm) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/2045931 Title: ps3 sixasis controller request pin to connect to bt Status in bluez package in Ubuntu: Won't Fix Bug description: Once my Ubuntu updated bluez package to 5.64-0ubuntu1.1 I was not able to connect my PS3 Sixasis controller via bluetooth.
