The latest update repairs 55 different flaws in the Android OS, four of which have been given a ‘critical’ rating due to their severity. Many of the others are also deemed high priority so users should update without delay.

Update your Samsung phone immediately

In addition to fixing all the flaws aforementioned, another reason to update your software as soon as possible is that it addresses the Samsung Exynos modem vulnerability which was exposed late last year by Google’s security team Project Zero.

The full extent of the vulnerability was revealed last month as it was announced that some Samsung phones had a flaw which meant that cybercriminals could remotely control a user’s phone using the built-in modem.

Project Zero found four critical issues on that occasion, which allowed a hacker to remotely compromise a phone at the modem level only by knowing the phone number. It was considered so serious at the time that Galaxy users were being urged to switch off their Wi-Fi until it was fixed.

Tim Willis, head of Google's Project Zero, explained, as per Android Police:

With limited additional research and development, we believe that skilled attackers would be able to quickly create an operational exploit to compromise affected devices silently and remotely.
