The pointer returned from tracehook_tracer_task() is only valid inside the rcu_read_lock. However the tracer pointer obtained is being passed to aa_may_ptrace outside of the rcu_read_lock critical section. Mover the aa_may_ptrace test into the rcu_read_lock critical section, to fix this. Kernels affected: 2.6.36 - 3.0 Reported-by: Oleg Nesterov <oleg@redhat.com> Cc: stable@kernel.org Signed-off-by: John Johansen <john.johansen@canonical.com> |
