- miduil 10mo agoPrevious discussion on ?a similar? vulnerability. That means there is yet another critical vulnerability from the same vendors, given the reporting date around ~August I hope this was addressed by Sony and Jabra around the same time. https://news.ycombinator.com/item?id=46453204 https://news.ycombinator.com/item?id=46453204 > Bluetooth Headphone Jacking: A Key to Your Phone [video] > 551 points > 223 comments > 21 days ago I wonder if some people could find more affected versions or whether there is some tool to detect more models, as I would doubt this is being nearly complete given how many vendors rely on this supplier.
- elnerd 10mo agoI have the impression this is not the same. In the linked video, they talked about unauthenticated functions in BLE if I recall correctly…
- miduil 10mo agoyes sorry, just updated my comment shortly before you replied. This is CVE-2025-36911, the other ones were CVE-2025-20700, CVE-2025-20701, CVE-2025-20702. Coincidentally a similar set of headphones affected. This one also has a pairing vulnerability, but I assume fast pair is on the BLE level: > To start the Fast Pair procedure, a Seeker (a phone) sends a message to the Provider (an accessory) indicating that it wants to pair. > [...] allowing unauthorised devices to start the pairing process [...] It's a pity that this is only awarded with $15k, this is a really bad vulnerability - which clearly required thoughtful investigation, publishing, reporting, ... and would have a much bigger audience in the exploit market.
