Name of the Vulnerable Software and Affected Versions
Android versions (affected versions not specified)
Description
The issue allows userspace to potentially map the kernel area to be writable, which can be easily exploited. This is because the 'remap pfn range' function may map out of size kernel memory, and the 'vma->vm page prot' can be controlled by userspace.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
