| 2009-11-10 17:18:27 | John Johansen | description | SRU Justification: This bug can cause confined process to oops at address 0. As reported by Tetsuo Handa on kernel-team mailing list: In aa_may_change_ptraced_domain, if (!tracer) cred == NULL, and put_cred(cred) will oops. This will only happen on exec if the task is marked as LSM_UNSAFE_PTRACE | LSM_UNSAFE_PTRACE_CAP, so should only happen to ptraced tasks that are confined. Fix this by returning directly from aa_may_change_ptrace_domain if there is now tracer. | SRU Justification: This bug can cause confined process to oops at address 0. This can occur when executing a process if the LSM_UNSAFE_PTRACE | LSM_UNSAFE_PTRACE_CAP flags are set. The likely hood of if/how often this will occur depends on if ptrace is being used.
