Vulnerability from fkie_nvd - Published: 2026-08-10 13:20 - Updated: 2026-08-19 17:20

Severity

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: media: stm32: dcmi: unregister notifier on probe failure dcmi_graph_init() registers the async notifier before dcmi_probe() toggles the reset line. If reset_control_assert() or reset_control_deassert() fails afterwards, probe returns through err_cleanup and the driver core will not call dcmi_remove(). Unregister the notifier before cleaning it up on that error path, matching the successful remove path and the V4L2 async notifier lifetime rules. [hverkuil: added Fixes tag]
