Millions of Samsung phones powered by the Exynos chipset, more precisely using Exynos with a Mali graphics chip (of which there are indeed many), are currently vulnerable to several exploits. One can cause kernel memory corruption, another can cause physical memory addresses to be exposed, and three others can lead to improper use of dynamic memory during program operation. He pointed it out team Google's Project Zero.
These vulnerabilities could allow an attacker to continue reading and writing physical pages after they have been returned to the system. Or in other words, an attacker with native code execution in an application could gain full access to the system and bypass the permissions system in Androidu.

The Project Zero team brought these security flaws to the attention of ARM (the maker of Mali graphics chips) in June and July. The company fixed them a month later, but at the time of writing, no smartphone manufacturers have released security patches to address them.

GPU Mali is found on smartphones of various brands, including Samsung, Xiaomi or Oppo. However, in reality, the above vulnerabilities were first discovered on the Pixel 6. Even Google has yet to patch them, despite being alerted by its team. These exploits do not affect Samsung devices powered by a Snapdragon chip or series Galaxy S22. Yes, the Korean giant's current lineup is available with Exynos in some markets, but it uses the Xclipse 920 GPU instead of the Mali graphics chip.
