CVE-2026-43140
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
HID: magicmouse: Do not crash on missing msc->input
Fake USB devices can send their own report descriptors for which the input_mapping() hook does not get called. In this case, msc->input stays NULL, leading to a crash at a later time.
Detect this condition in the input_configured() hook and reject the device.
This is not supposed to happen with actual magic mouse devices, but can be provoked by imposing as a magic mouse USB device.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
