Linux Kernel up to 6.1.1 power power_supply_get_battery_info null pointer dereference

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 5.4.228/5.10.162/5.15.85/6.0.15/6.1.1. This issue affects the function power_supply_get_battery_info of the component power. The manipulation with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: power: supply: fix null pointer dereferencing in power_supply_get_battery_info when kmalloc() fail to allocate memory in kasprintf(), propname will be NULL, strcmp() called by of_get_property() will cause null pointer dereference. So return ENOMEM if kasprintf() return NULL pointer.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2022-50276 since 09/15/2025. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 319448 (EulerOS Virtualization 2.13.1 : kernel (EulerOS-SA-2026-2132)), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 5.4.229, 5.10.163, 5.15.86, 6.0.16 or 6.1.2 eliminates this vulnerability. Applying the patch 8ea68b4e3fa9392ef9dae303abc8735a033c280f/5beadb55f4e36fafe5d6df5dcd5f85d803f3f134/d21534ab4fd7883e1c8037a76671d4e8b6ea14cb/279af90e65cbdb3e5c4519b0043324d7876bc5ec/b8131efb89d9f837c9244f900f0fc2699fd1181d/104bb8a663451404a26331263ce5b96c34504049 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.
