Machine-written summary

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

Linux kernel versions from 6.1.191 up to 6.1.*, 6.6.160 up to 6.6.*, 6.12.114 up to 6.12.*, and 6.18.57 up to 6.18.* are listed as unaffected, and the affected range is given as 6.15 onward, with several specific commit ranges also listed. An attacker with the ability to trigger SCMI child device unregistration concurrently with a destroy operation could cause a use-after-release of the device, though the source gives few details about the exact impact. Upgrade to a fixed kernel version from the stable branch for your release; the source does not state a workaround.
