GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

FKIE_CVE-2022-50489

Vulnerability from fkie_nvd - Published: 2025-10-04 16:15 - Updated: 2026-06-17 05:23
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/mipi-dsi: Detach devices when removing the host Whenever the MIPI-DSI host is unregistered, the code of mipi_dsi_host_unregister() loops over every device currently found on that bus and will unregister it. However, it doesn't detach it from the bus first, which leads to all kind of resource leaks if the host wants to perform some clean up whenever a device is detached.
