CVE-2024-42230 is a vulnerability in the Linux kernel's powerpc/pseries architecture where the scv instruction can cause a kernel crash during kexec. The issue arises because kexec disables the Asynchronous Interrupt Logic (AIL) before other CPUs are shut down, allowing CPUs to execute scv instructions after AIL is disabled, leading to an unexpected interrupt and kernel crash. The fix changes the kexec sequence to disable AIL only after other CPUs have been brought down.
