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. ]
