Linux Kernel Sierra USB Net Driver Vulnerability

Vulnerability

A vulnerability in the Linux kernel's Sierra USB net driver has been addressed. The issue arose because the driver failed to verify that the third endpoint was an interrupt input, despite correctly checking for the presence of three endpoints and ensuring that the bulk in and out endpoints were available. This oversight has been corrected.

Impact

The vulnerability could lead to improper handling of USB endpoints, potentially causing issues in data transmission or device communication.
