No. Please do not cc <secalert at redhat.com> on the upstream kernel patches.
It is meant for reporting security issues only.

Going through the patches here

1. Issues in ../staging/ drivers are not considered for CVE, they are not to be
used
in production environment.

2. Many of the patches listed fix NULL pointer dereference when memory
allocation
fails and returns NULL.

3. Do you happen to have reproducers for these issues? Could an unprivileged
user trigger them?

Generally CVE is assigned after confirming that a given issue really is a
security issue. And it may
have impact ranging from information leakage, DoS to privilege escalation or
maybe arbitrary code
execution. Every NULL pointer dereference is not security issue.


Hope it helps. Thank you.
