Description
Problem Description: The callee-save registers are used by kernel and for some of them (%r8, %r10, and for non-PTI configurations, %r9) the content is not sanitized before return from syscalls, potentially leaking sensitive information. Impact: Typically an address of some kernel data structure used in the syscall implementation, is exposed.
