## Machine-written summary

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

> The Linux kernel's cfg80211 wireless subsystem is affected in versions from 5.0 before the fixes in the listed kernel branches. When a P2P device or NAN interface is stopped while a peer measurement (PMSR) request is pending, the request is not aborted in the driver first, so the driver can keep a stale request and use it later. The source gives few details about the attack conditions or impact. Upgrade to a fixed kernel version: 6.1.191 or later in the 6.1 series, 6.6.160 or later, 6.12.114 or later, or 6.18.52 or later.
