CVE-2025-9815 Details
Description
A weakness has been identified in alaneuler batteryKid up to 2.1 on macOS. The affected element is an unknown function of the file PrivilegeHelper/PrivilegeHelper.swift of the component NSXPCListener. This manipulation causes missing authentication. It is possible to launch the attack on the local host. The exploit has been made available to the public and could be exploited.
A vulnerability exists in alaneuler batteryKid versions through 2.1 on macOS. The issue arises from a root-privileged XPC helper that lacks authentication for critical functions. This helper, registered with NSXPCListener, allows any local user to perform privileged operations on the System Management Controller (SMC) without authorization. Exploitation of this vulnerability can disrupt normal hardware functions, such as battery charging and power adapter connectivity, potentially leading to battery damage and overheating.
To address this vulnerability, it is recommended to validate connections using auditToken, restrict exposed methods to a minimal, readonly subset for non-privileged clients, add authentication logic before accepting requests, and use SMJobBless properly to ensure user consent and authorization for elevated operations.
