Summary

CVE-2023-52978 is a Linux kernel vulnerability affecting configurations without the RISCV ISA (Instruction Set Architecture). When using kprobes, the kernel could panic due to an ebreak instruction breaking the original code at an illegal position. This issue resulted in a stack corruption and a kernel panic. To prevent such occurrences, the patch introduces arch_check_kprobe in arch_prepare_kprobe, ensuring only valid probe positions are used.
