Loading vulnerability…
CVE-2025-48638 is a critical elevation-of-privilege vulnerability in the Android kernel affecting the protected KVM (pKVM) subsystem. The flaw is located in the __pkvm_load_tracing function in trace.c and is caused by improper input validation that can result in an out-of-bounds write. By supplying crafted input that reaches this code path, a local attacker can corrupt memory in kernel context. Because the issue resides in pKVM, exploitation may undermine a security boundary intended to isolate sensitive code and data on Android devices.
