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

The driver checks for having three endpoints and
having bulk in and out endpoints, but not that
the third endpoint is interrupt input.
Rectify the omission.

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is in the Linux kernel's USB network driver for Sierra devices. The driver was supposed to check that there are three endpoints: bulk in, bulk out, and an interrupt input endpoint. However, it did not verify that the third endpoint is specifically an interrupt input endpoint, which was an omission. This vulnerability has been resolved by adding the missing check.
