CVE-2025-48637 is a critical elevation-of-privilege vulnerability in the Android kernel's protected KVM (pKVM) subsystem. The flaw is present in multiple functions within mem_protect.c, where an integer overflow can cause an out-of-bounds write. Because pKVM is part of Android's virtualization-based isolation model, memory corruption in this component can undermine security boundaries enforced by the kernel. Successful exploitation does not require user interaction and can be triggered by a local attacker without additional execution privileges.
