Samsung has acknowledged the vulnerability reported earlier this week in kernel of some Samsung Exynos chipsets and claimed that a fix is coming soon.
Samsung issued the following statement to Android Central:
Samsung is aware of the potential security issue related to the Exynos processor and plans to provide a software update to address it as quickly as possible.
The issue may arise only when a malicious application is operated on the affected devices; however, this does not affect most devices operating credible and authenticated applications.
Samsung will continue to closely monitor the situation until the software fix has been made available to all affected mobile devices.
The exploit was revealed earlier this week by user alephzain over at XDA
who claimed that any user application could access all physical memory available to the device. The exploit affects the Exynos 4210 and 4412 chips, which power some of Samsung's most popular devices including Galaxy S II, Galaxy S III, Galaxy Note, Galaxy Note II and Galaxy Note 10.1.
