Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The Linux kernel ALSA pcxhr driver is affected from version 3.18 until it is fixed. During probe, an interrupt handler can run against mutexes that are not yet initialized, and the source gives few details on the required access or the resulting impact. Upgrade to 5.10.273, 5.15.221, 6.1.188, or 6.6.157, or to a later release in those series.
