All Android users placed on red alert - you must check your settings 'immediately'

Anyone with an Android phone in their possession must be on high alert and make sure their settings are fully up to date. That's the latest warning from security experts after a worrying bug has been found hiding within this hugely popular operating system. Google has now fixed the error, but not before it was handed the dreaded zero-day stamp.

That tag basically means the glitch has already been spotted by hackers and is being actively exploited in the wild. That's why it's so vital everyone makes a quick check without delay.

Explaining more, Adam Boynton, Senior Security Strategy Manager EMEIA at firm Jamf, said: “The latest Android Security Bulletin contains a fix for an actively exploited vulnerability, CVE-2025-27363, therefore we advise all Android users to update their devices immediately."

Google always releases monthly patches, which usually fix minor bugs and glitches. However, sometimes the problems are a little more serious and that's why it's vital all phone users make sure they keep on top of installing updates.

So what happens if you are targeted by the latest issue?

“The fixed bug is an out-of-bounds memory vulnerability in the FreeType software,” Jamf’s Boynton explained. “FreeType is a core component of Android devices because it renders fonts and is therefore an attractive target for cybercriminals. Exploiting the vulnerability could allow an attacker to gain control of the entire system without requiring elevated privileges.

“Although this is a targeted attack, most likely targeting high-value individuals, we strongly recommend that all users update their Android OS. The bug has been exploited since March, and its zero-click nature means that criminals can exploit the vulnerability without the user even being aware.”

Google usually rolls out its updates to Pixel devices first with other manufacturers such as Samsung, OnePlus and Honor following soon after the initial release.

No matter what phone you have in your pocket. It's a good idea to head to the settings menu this week and make sure things are fully updated.
