Samsung monthly updates: December 2025 security patch details

[phillynews215]

Samsung has revealed details about the next monthly security update for Galaxy smartphones and tablets. The December 2025 security patch is one of the most substantial this year, delivering fixes for more than five dozen vulnerabilities.



The new patch fixes 57 vulnerabilities—six rated critical and the rest considered high-risk—that affect the core Android operating system. In addition to Google’s fixes, Samsung has patched 11 security flaws that specifically affect its own phones and tablets.



Some of the most serious issues involved out-of-bounds reads and writes in the fingerprint system, bootloader, and image codec libraries, which could let attackers access or overwrite data they shouldn’t be able to.



The patch also addresses a flaw in Dynamic Lockscreen that could have let other apps access its files, and a validation bug in Samsung’s radio interface layer that could allow unintended memory writes.



As usual, Samsung will roll out the new security patch to eligible devices gradually throughout the month. The November 2025 update’s rollout was slower than usual because the company was focused on delivering the One UI 8 (Android 16) upgrade, but with that major release now out of the way, the December patch will hopefully arrive more quickly, especially considering how extensive it is.



To download updates on your Galaxy phone or tablet, navigate to Settings > Software update and tap Download and install. If you prefer installing updates manually, you can download firmware for your device from SamMobile and flash it using a Windows PC.
