vulnerability found in Samsung Exynos 4 kernel

Tuesday, December 18, 2012

A new kernel exploit has been found that affects some Samsung Exynos 4 chipsets which powers a list of Samsung devices including international Galaxy s3, Galaxy S2, international Galaxy Note 1 and 2, and more…

The bug in the kernel source that lets users have access to the device RAM, and then he is free to dump it and see what's there or inject new processes of his own. An app could be built with this exploit hidden inside, rooting your phone without your knowledge. It then could use the new elevated permissions to send data off to somewhere else, or do any number of equally malicious things you can do with root access.

Samsung informed us that it is "currently in the process of conducting an internal review" into the matter.

In the meantime a developer has made a quick solution for this bug until Samsung solution reach all affected devices by OTA update.
