== Comment: #0 - Breno Leitao <[email protected]> - 2017-06-28 08:00:40 ==
When a process accesses an invalid EA it results in a SEGV signal being
sent to the process, which typically results in the process being
killed. Process death isn't instantaneous however, the process may catch
the SEGV signal and continue somehow, or the kernel may start writing a
core dump for the process, either of which means it's possible for the
process to be preempted while its processing the SEGV but before it's
been killed.
We need to have this fix on kernel 4.4 and 4.8:
