Tens of millions of Samsung telephones powered via Exynos, or extra particularly, Exynos chipsets with Mali GPUs (of which there are lots of), are these days at risk of a number of safety exploits. One can result in kernel reminiscence corruption, some other to bodily reminiscence addresses being disclosed, and 3 different vulnerabilities can result in a bodily web page us-after-free situation.

Or in different phrases, an attacker with local code execution in an app may just acquire complete get entry to to the machine and bypass the permission type in Android OS. (by means of Google Mission 0)
ARM fastened the problem, however smartphone producers have no longer
Those safety flaws found out via Mission 0 had been dropped at ARM’s consideration in June and July. ARM fastened those Mali-related safety flaws a month later, however as of this writing, no smartphone distributors have implemented safety patches to deal with those vulnerabilities.
The Mali GPU from ARM may also be present in smartphones throughout other manufacturers, together with Samsung, Xiaomi, and Oppo.

Google hasn’t patched this vulnerability both, in spite of Mission 0’s efforts to convey the issue to mild.
This vulnerability doesn’t worry Samsung gadgets powered via Snapdragon or the Galaxy S22 sequence. Sure, the latter has an Exynos chipset in some markets, nevertheless it makes use of an Xclipse 920 graphics chip somewhat than a Mali GPU.
