CVE-2026-23170

Service interrupt via leaked DDC device references

Published Feb 14, 2026 · Updated Feb 14, 2026

Memory leak in the IMX TV encoder driver in affected Linux Kernel branches allows local users to interrupt service through resource exhaustion. The imx_tve_probe function retains the reference returned for the DDC I2C adapter because probe failures and driver unbind do not call put_device. Reachability requires an IMX TV encoder configuration with a DDC device and lifecycle events that repeatedly leak references, progressively consuming kernel resources.
