Vulnerability from github – Published: 2024-05-21 15:31 – Updated: 2025-04-30 15:30

Details

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

bus: mhi: core: Validate channel ID when processing command completions

MHI reads the channel ID from the event ring element sent by the device which can be any value between 0 and 255. In order to prevent any out of bound accesses, add a check against the maximum number of channels supported by the controller and those channels not configured yet so as to skip processing of that event ring element.

Severity

7.8 (High)
