## Machine-written summary

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

> The Linux kernel's nl80211 wireless configuration interface, in the color-change beacon handling path, can leak memory when beacon parsing fails partway through. The source does not describe how an attacker would reach this path or what impact a leak would have. The fix is in several stable kernel branches; the source lists unaffected versions from 5.16 onward on the 6.1, 6.6, 6.12 and 6.18 series, and affected versions before those, so upgrade to a fixed kernel release.
