Samsung has begun rolling out a software patch to address a major security flaw with its Exynos processor that leaves a handful of Android handsets vulnerable to attack. The update is first reaching Galaxy S III owners in the United Kingdom, but we would expect Samsung to be working hard to make this one available worldwide as quickly as possible.

Samsung has vowed to patch a major vulnerability discovered in its Exynos kernel that could allow certain Android devices to be wiped or bricked by a malicious application. The flaw was discovered earlier this week, and the Korean company promises to release a software update to address it “as quickly as possible.”
