CVE-2026-68211

Description

A flaw was found in the Linux kernel's stm32-dcmipp media driver. When the start_streaming() function fails to initialize, it does not properly return previously queued buffers. This oversight can lead to a leak of these buffers, potentially causing resource exhaustion and affecting system stability.

Déclaration

This issue affects STM32 DCMIPP camera pipeline. start_streaming() failure does not return queued vb2 buffers. Embedded STM32 platforms only.

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Les mesures et les scores CVSS suivants sont préliminaires et sujets à révision.
