## Machine-written summary

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

> The ALSA harmony sound driver in the Linux kernel is affected from 2.6.12 until fixed. The interrupt handler is registered before the driver's locks are initialized, so a pending interrupt can run it with uninitialized locks; the source gives few details on attacker requirements. Upgrade to a fixed kernel such as 5.10.273, 5.15.221, 6.1.188, 6.6.157, or a later release in those series.
