Description OSIDB Bzimport 2025-07-28 12:01:57 UTC 
In the Linux kernel, the following vulnerability has been resolved:

usb: net: sierra: check for no status endpoint

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.
