Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The Linux kernel tracing options files did not take a reference to their trace instance when opened, so removing that instance while a file is open can cause a use-after-free and kernel crash. Affected versions start at 2.6.30; upgrade to 6.1.191, 6.6.160, 6.12.112, 6.18.52, or a later release in those series.
