VB-Audio Matrix and Matrix Coconut (versions ending in 1.0.2.2 and 2.0.2.2 and earlier, respectively), contain a local privilege escalation vulnerability in the VBMatrix VAIO virtual audio driver (vbmatrixvaio64*_win10.sys). The driver allocates a 128-byte non-paged pool buffer and, upon receiving IOCTL 0x222060, maps it into user space using an MDL and MmMapLockedPagesSpecifyCache. Because the allocation size is not page-aligned, the mapping exposes the entire 0x1000-byte kernel page containing the buffer plus adjacent non-paged pool allocations with read/write permissions. An unprivileged lo
