Linux Kernel up to 6.0.7 s5p_cec buffer overflow

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 was found in Linux Kernel up to 6.0.7 and classified as critical. Affected by this issue is an unknown code of the component s5p_cec. The manipulation with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: media: s5p_cec: limit msg.len to CEC_MAX_MSG_SIZE I expect that the hardware will have limited this to 16, but just in case it hasn't, check for this corner case.

The advisory is shared for download at git.kernel.org. This vulnerability is handled as CVE-2022-49035 since 08/22/2024. The exploitation is known to be easy. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 01/22/2025).

The vulnerability scanner Nessus provides a plugin with the ID 214453 (SUSE SLES15 Security Update : kernel (SUSE-SU-2025:0202-1)), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 4.9.333, 4.14.299, 4.19.265, 5.4.224, 5.10.154, 5.15.78 or 6.0.8 eliminates this vulnerability. Applying the patch 7ccb40f26cbefa1c6dfd3418bea54c9518cdbd8a/fc0f76dd5f116fa9291327024dda392f8b4e849c/a2728bf9b6c65e46468c763e3dab7e04839d4e11/4a449430ecfb199b99ba58af63c467eb53500b39/1609231f86760c1f6a429de7913dd795b9faa08c/cbfa26936f318b16ccf9ca31b8e8b30c0dc087bd/2654e785bd4aa2439cdffbe7dc1ea30a0eddbfe4/93f65ce036863893c164ca410938e0968964b26c 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.
