Fixes have also been released for 67 vulnerabilities listed as high priority and six medium priority vulnerabilities. A vulnerability in the previous security update has also been fixed with this update.
Some of the issues fixed with the update
This update fixes an issue with the “Notification service” on Galaxy phones. This issue could have allowed attackers to access users’ personal information. Galaxy devices running Android 11 to Android 14 were affected by this issue.

An issue that allowed Samsung DeX users to access other users’ notifications in a multi-user environment has also been fixed with this update. It is unclear whether the January security update brings back the previously removed screen burn-in protection feature on affected phones.
