CVE-2026-0027 is a critical local elevation-of-privilege vulnerability in the Android kernel virtualization stack, associated with the protected Kernel-based Virtual Machine (pKVM) subsystem. The flaw is located in the arm-smmu-v3 implementation, specifically in the smmu_detach_dev function, where a use-after-free condition can result in an out-of-bounds write. This memory-safety error can corrupt kernel memory during device detachment handling in the SMMU path. On affected Android builds, successful exploitation can allow escalation from an already privileged local context into higher-privileged execution within the system or virtualization boundary.
