In this post I’ll exploit CVE-2022-20186, a vulnerability in the Arm Mali GPU kernel driver and use it to gain arbitrary kernel memory access from an untrusted app on a Pixel 6. This then allows me to gain root and disable SELinux. This vulnerability highlights the strong primitives that an attacker may gain by exploiting errors in the memory management code of GPU drivers.

In this post I’ll exploit CVE-2022-1134, a type confusion in Chrome that I reported in March 2022, which allows remote code execution (RCE) in the renderer sandbox of Chrome by a single visit to a malicious site. I’ll also look at some past vulnerabilities of this type and some implementation details of inline cache in V8, the JavaScript engine of Chrome.

In this post I’ll exploit CVE-2022-22057, a use-after-free in the Qualcomm gpu kernel driver, to gain root and disable SELinux from the untrusted app sandbox on a Samsung Z flip 3. I’ll look at various mitigations that are implemented on modern Android devices and how they affect the exploit.
