Linux Kernel up to 7.2.4 i2c adapter panel-edp.c 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 6.1.187/6.6.156/6.12.109/6.18.50/7.2.4. Affected is some unknown processing of the file panel-edp.c of the component i2c adapter. 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. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: drm/panel-edp: fix i2c adapter leak on probe failure Make sure to drop the i2c adapter reference on probe failure (e.g. probe deferral) and on driver unbind also if a devicetree redundantly uses the 'ddc-i2c-bus' property to point to the aux ddc bus.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2026-89824 since 09/11/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 09/16/2026). This vulnerability is assigned to T1499 by the MITRE ATT&CK project.
