Summary

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

wifi: ath9k: don't allow to overwrite ENDPOINT0 attributes

A bad USB device is able to construct a service connection response message with target endpoint being ENDPOINT0 which is reserved for HTC_CTRL_RSVD_SVC and should not be modified to be used for any other services.

Reject such service connection responses.

Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
