Details
A vulnerability classified as critical has been found in Google Android (Smartphone Operating System) (version unknown). This affects the function remap_pfn_range of the component Kernel. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:
'remap_pfn_range' here may map out of size kernel memory (for example, may map the kernel area), and because the 'vma->vm_page_prot' can also be controlled by userspace, so userspace may map the kernel area to be writable, which is easy to be exploitedProduct: AndroidVersions: Android SoCAndroid ID: A-233972091
