CVE-2026-90357

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

State: Published
Severity: 8.8 High

Description

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.
