CVE-2022-20238

'remappfnrange' here may map out of size kernel memory for example, may map the kernel area, and because the 'vma-vmpageprot' 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:...

CVE-2022-20239

CVE-2022-20239 is an Android kernel vulnerability inherited from a memory-mapping flaw in remap_pfn_range that can let userspace map the kernel area as writable. Documents consistently describe the issue as kernel memory mapping in remap_pfn_range, with potential for local/remote-like impact depe...

CVE-2022-20238

CVE-2022-20238 describes a kernel memory mapping flaw in Android where remap_pfn_range can map memory outside the intended region because vma->vm_page_prot is user-controllable. The result is a potential writable mapping of kernel memory, enabling exploitation per several sources (Android kern...
