DescriptionNVD

In the Linux kernel, the following vulnerability has been resolved:

media: mtk-mdp: Fix error handling in probe function

Add mtk_mdp_unregister_m2m_device() on the error handling path to prevent resource leak.

Add check for the return value of vpu_get_plat_device() to prevent null pointer dereference. And vpu_get_plat_device() increases the reference count of the returned platform device. Add platform_device_put() to prevent reference leak.

AnalysisAI

Resource management flaws in the Linux kernel MediaTek MDP driver allow local authenticated attackers with low privileges to trigger memory corruption via improper error handling during device probe initialization, potentially escalating to kernel code execution. Multiple stable kernel branches (5.10.x through 7.0) are affected, with vendor patches released across all maintained versions. …

Sign in for full analysis, threat intelligence, and remediation guidance.

RemediationAI

Within 24 hours: Identify all systems running Linux kernel versions 5.10.x through 7.0 with MediaTek MDP drivers enabled (check kernel config and dmesg logs). Within 7 days: Prioritize patching of internet-facing or multi-user systems; apply vendor-released kernel updates to affected stable branches. …
