Detailsinfo

A vulnerability was found in Linux Kernel up to 6.0.2. It has been declared as critical. Affected by this vulnerability is the function mipi_dsi_host_unregister of the component mipi-dsi. The manipulation with an unknown input leads to a infinite loop vulnerability. The CWE definition for the vulnerability is CWE-835. The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop. As an impact it is known to affect availability. The summary by CVE is:

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.

The advisory is shared at git.kernel.org. This vulnerability is known as CVE-2022-50489 since 10/04/2025. Technical details are known, but no exploit is available.
