Publication date: 2026-06-16

Last updated on: 2026-06-16

Assigner: Google Devices

Description
In OSMMapPMRGeneric of pmr_os.c, there is a possible way to leverage a system call to system call to maliciously expand the VMA out of bounds due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Executive Summary

This vulnerability exists in the OSMMapPMRGeneric function of the pmr_os.c file. It involves a logic error that allows a system call to maliciously expand the Virtual Memory Area (VMA) out of its intended bounds.

Because of this logic error, an attacker can exploit the system call to manipulate memory boundaries improperly.

This flaw can be leveraged without any user interaction and does not require additional execution privileges.

Impact Analysis

The primary impact of this vulnerability is local escalation of privilege.

An attacker who already has local access to the system could exploit this vulnerability to gain higher privileges than originally granted.

This could allow the attacker to perform unauthorized actions on the system without needing additional execution privileges or user interaction.
