Software update reportedly fixes Samsung Galaxy S3 security flaw

A new software update pushed across Samsung Galaxy S3 devices has apparently plugged a security hole that was found in the best-selling smartphone and a number of its Galaxy peers last month.

The flaw, which specifically lay within the ARM-based Exynos 4 SoC used in the S3 as well as the Galaxy Note and Galaxy S2, ran the danger of giving apps access to user data and exposing the handset to malware and bricking if exploited. The flaw allowed system permissions to be bypassed, enabling apps to inject malicious code into the kernel or steal data from the phone’s RAM.

But according to Sammobile, the latest system update on the Galaxy S3 has fixed the problem – for this model at least. The site also reports that the sudden death issue flagged up by some users may now have been rectified too.

Samsung has yet to confirm the effect of the updates, or whether the fixes can be applied outside the UK or on the other exposed Exynos 4 devices.
