**Significant Security Issues and More Are Being Resolved for All Other Galaxy S25 Devices**
Samsung has begun the deployment of its stable January 2026 security update for Galaxy S25 devices that are not part of the One UI 8.5 beta program. This update tackles a range of security flaws, focusing on correcting problems in the file system and other essential areas. Earlier in the month, a comparable update was issued for users of One UI 8.5 Beta 3.
The most recent security patch for the Galaxy S25 series, which includes the S25, S25 Plus, S25 Ultra, and S25 FE, was noted on January 13 by SamMobile. The update, as detailed on Samsung’s Security Updates page, features 21 fixes, with 19 marked as “High” priority and two as “Critical.”
Among the resolutions, Samsung addresses CVE-2026-20969, a weakness that allows inappropriate file access with system permissions. Additional patches fix problems related to out-of-bounds memory access and Carrier Relock circumventions.
Overall, the patch encompasses around 55 fixes for Samsung’s flagship devices. Google’s Android Security Bulletin provides further improvements, including a crucial fix for devices equipped with Dolby components.
The patch, labeled as vBYLR, is first being rolled out in South Korea, with plans to extend to the U.S., Europe, and other areas soon.
This is the second January update for the Galaxy S25 series, following a previous release for One UI 8.5 Beta participants. The earlier update, a considerable 1.2GB download, dealt with several bugs, such as lock screen issues, gallery lag, and widget problems.
The One UI 8.5 beta program started later than expected, likely owing to Samsung’s concentration on the upcoming S26 series. The new software update, anticipated to launch alongside the Galaxy S26, promises considerable improvements over the smaller 8.1 update, with a wider rollout scheduled for other models, including the S25.
