Local Privilege Escalation in Android Kernel pKVM init_pkvm_hyp_vcpu
CVE-2025-48623 is a critical elevation-of-privilege vulnerability in the Android kernel's protected KVM (pKVM) subsystem. According to the provided content, the flaw is located in the function init_pkvm_hyp_vcpu in pkvm.c, where improper input validation can result in an out-of-bounds write. This memory corruption condition may allow a local attacker to corrupt adjacent memory in the pKVM context and break intended isolation guarantees. The issue is described as requiring no additional execution privileges and no user interaction for exploitation.
