lntrx/cve-2021-28663Proof-of-concept exploit for CVE-2021-28663, a design flaw in the Mali GPU Android kernel driver enabling arbitrary read via memory alias and eviction manipulation.
A basic PoC leak for CVE-2021-28663 (Internal of the Android kernel backdoor vulnerability)
This is a basic PoC for CVE-2021-28663. A design flaw in Mali GPU Android Kernel Driver.
GPU_VA and also mmap to it so we can get virtual addr for phys pages.mmap so gpu_mapping remains as 1GPU_VA to BASE_MEM_DONT_NEED. Mali will make them evictablereg for aliased page, now we can mmap to it. This will give us RDONLY access from CPU
