Samsung has started rolling out the first security patch of its flagship phones for January 2024. Users have already spotted the package in Europe. Galaxy S23 owners can search for the firmware version S91xBXXS3BWL3while the S22 and S21 devices are expected to receive releases S90xBXXS7DWL3 AND G99xBXXS9FWL9 respectively. The update appears to weigh in at around 400MB and feels very “dense”, for lack of a better term.
Looking at the official patch notes, we can see that Samsung has fixed one critical security issue and 67 others labeled as “high” priority by the Korean giant.
Reading the notes themselves a bit, we see that there was apparently a vulnerability in Samsung’s Bluetooth pairing process that would allow attackers to establish a pairing process without user interaction. Another interesting bug could potentially allow Samsung DeX users in multi-user environments to access another user’s notifications.
It’s unclear whether this update includes a screen burn-in protection measure that Samsung previously promised was coming in January.
As mentioned, the new January security patch has already been spotted on flagship Galaxy devices in Europe and is expected to arrive in the US shortly. In addition to the device families already mentioned, the patch should also arrive in the same wave on the Galaxy Z Fold5, Z Flip5, Z Fold4, Z Flip4, A54 and Note20. Interestingly, non-FE Edition devices currently appear to fall into this wave.
