Google has patched a vulnerability being exploited in the wild to root Nexus 5 Android devices. The public exploit—a rooting application—was privately disclosed to Google on March 15 by Zimperium researchers, and a less than a month after CORE Team researchers reported that CVE-2015-1805, which was patched in 2014 in the Linux kernel, also affects...

A rooting application has been found in the wild targeting Nexus mobile devices using a local privilege escalation vulnerability patched two years ago in the Linux kernel that remains unpatched in Android. Researchers at Zimperium, the same company that discovered last summer’s Stagefright flaws affecting Android, privately disclosed to Google last Tuesday they found an...
