+ <h1>Problem Description:</h1>
+ <p>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.</p>
+ <h1>Impact:</h1>
+ <p>Typically an address of some kernel data structure used
+ in the syscall implementation, is exposed.</p>
