## Overview

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

wifi: mt76: mt7915: unlink TWT flow if the MCU rejects the agreement

The flow is added to dev->twt_list before sending the agreement to the
firmware, but the error path leaves it linked while flowid_mask is
never set. The flow slot can then be reused and memset while still on
the list, corrupting twt_list, and station removal leaves a dangling
entry behind that mt7915_mac_twt_sched_list_add() later walks.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
