This is an issue that allows unentitled root to read kernel frame
|
|
pointers, which might be useful in combination with a kernel memory
|
|
corruption bug.
|
|
|
|
By design, the syscall stack_snapshot_with_config() permits unentitled
|
|
root to dump information about all user stacks and kernel stacks.
|
|
While a target thread, along with the rest of the system, is frozen,
|
|
machine_trace_thread64() dumps its kernel stack.
|
|
machine_trace_thread64() walks up the kernel stack using the chain of
|
|
saved RBPs. It dumps the unslid kernel text pointers together with
|
|
unobfuscated frame pointers.
|
|
|
|
The attached PoC dumps a stackshot into the file stackshot_data.bin
|
|
when executed as root. The stackshot contains data like this:
|
|
|
|

|
The addresses on the left are unslid kernel text pointers; the
|
|
addresses on the right are valid kernel stack pointers.
|
