CVE-2021-0942

The path in this case is a little bit convoluted. The end result is that via an ioctl an untrusted app can control the ui32PageIndex offset in the expression:sPA.uiAddr = pagetophyspsOSPageArrayData-pagearrayui32PageIndex;With the current PoC this crashes as an OOB read. However, given that the O...
