## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> Linux kernel versions from 5.19 until fixed are affected by a bug in the mt76 mt7915 Wi-Fi driver, which leaks interface state after a failed add and can dereference a stale monitor pointer in testmode. The source gives few details on what an attacker needs. Upgrade to 6.1.191, 6.6.160, 6.12.110, or 6.18.52 or later in those series.
