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 6.2.2. It has been rated as critical. This issue affects the function mtk_drm_bind of the component mediatek. Using CWE to declare the problem leads to CWE-416. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Clean dangling pointer on bind error path mtk_drm_bind() can fail, in which case drm_dev_put() is called, destroying the drm_device object. However a pointer to it was still being held in the private object, and that pointer would be passed along to DRM in mtk_drm_sys_prepare() if a suspend were triggered at that point, resulting in a panic. Clean the pointer when destroying the object in the error path to prevent this from happening.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2023-53388 since 09/17/2025. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 12/11/2025).

The vulnerability scanner Nessus provides a plugin with the ID 265906 (Linux Distros Unpatched Vulnerability : CVE-2023-53388), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 4.19.276, 5.4.235, 5.10.173, 5.15.99, 6.1.16 or 6.2.3 eliminates this vulnerability. Applying the patch 9a48f99aa7bea15e0b1d8b0040c46b4792eddf3b/a161f1d92aabb3b8463f752bdc3474dc3a5ec0e5/6a89ddee1686a8872384aaa9f0bcfa6b675acd86/49cf87919daeeeeeb9e924c39bdd9203af434461/7b551a501fa714890e55bae73efede1185728d72/f3887c771576c5d740c5c5b8bf654a8ab8020b7d/36aa8c61af55675ed967900fbe5deb32d776f051 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.

The vulnerability is also documented in the databases at Tenable (265906) and CERT Bund (WID-SEC-2025-2092). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
