Affected users will need to re-flash an instance of the Android operating system.

Google found a rooting application that exploits the vulnerability in order to root Nexus 5 and 6 handsets. All un-patched Android phones are affected however.

The Alphabet subsidiary did not say whether the application was malicious or an app to help users to root their Nexus devices.

Google has blocked the rooting app in its Play Store, while users of the latest Android operating systems will receive security flags warning of the rooting capabilities of the app.

The search tsar distributed the patch to its phone manufacturer partners on 15 March ahead of today’s general release.

“Google has become aware of a rooting application using an un-patched local elevation of privilege vulnerability in the kernel on some Android devices,” the company said in an advisory.

“This is a known issue in the upstream Linux kernel that was fixed in April 2014 but wasn’t called out as a security fix.

“On February 19, 2016, C0RE Team notified Google that the issue could be exploited on Android and a patch was developed to be included in an upcoming regularly scheduled monthly update.”

Android devices with a security patch level of 2 April are patched against the flaw.
