Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-11 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

HID: prodikeys: Check presence of pm->input_ep82

Fake USB devices can send their own report descriptors for which the input_mapping() hook does not get called. In this case, pm->input_ep82 stays NULL, which leads to a crash later.

This does not happen with the real device, but can be provoked by imposing as one.

Severity ?

5.5 (Medium)
