Description
This module exploits a race condition in the Linux kernel do_exit() teardown path affecting __ptrace_may_access().
During process termination, privileged file descriptors may remain accessible through pidfd_getfd() after task->mm becomes NULL, allowing sensitive file disclosure from privileged SUID binaries such as chage.
This module targets chage to disclose /etc/shadow.
This module performs information disclosure only and does not create a new session.
