Summary
In the Linux kernel, the following vulnerability has been resolved: kprobes/x86: Use copy_from_kernel_nofault() to read from unsafe address Read from an unsafe address with copy_from_kernel_nofault() in arch_adjust_kprobe_addr() because this function is used before checking the address is in text or not. Syzcaller bot found a bug and reported the case if user specifies inaccessible data area, arch_adjust_kprobe_addr() will cause a kernel panic. [ mingo: Clarified the comment. ]
