Linux Kernel up to 6.1.1 clk _samsung_clk_register_pll memory leak

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, was found in Linux Kernel up to 6.1.1. This affects the function _samsung_clk_register_pll of the component clk. The manipulation with an unknown input leads to a memory leak vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: clk: samsung: Fix memory leak in _samsung_clk_register_pll() If clk_register() fails, @pll->rate_table may have allocated memory by kmemdup(), so it needs to be freed, otherwise will cause memory leak issue, this patch fixes it.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2022-50449 since 09/17/2025. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 302405 (EulerOS 2.0 SP10 : kernel (EulerOS-SA-2026-1313)), which helps to determine the existence of the flaw in a target environment.
