Not sure this issue can be triggered by a non-privileged user.

this one should get a CVE id i think. looking at only two data
points
(2.6.26 and 2.6.32), i've found the vulnerable code present in
both.
if i'm not mistaken, redhat has had supported releases in that
range.

Was discussing this with another colleague, that it seems possible
to
trigger this issue with a non-privileged user. And yes, I agree
that
this should have a CVE name assigned. Thanks.

pgrp member in struct tty_struct was converted to struct pid in commit

ab521dc0, so kernels of version v2.6.26-rc1 and above are affected by
this.
