Thanks for the extra background, Jason, as well as the reference to the upstream patch proposal.
For the record, although this is not an RHEL-specific bug, we had filed the bug with RedHat, since that's where we ran into it, hence the reference to the RH bug number.
Also, Fedora is upstream from RHEL, but RHEL is free to make additional modifications, hence my assertion that they are not the same kernel. I was sure that the bug gets at least that high up, but I wasn't certain if it occurred higher upstream.
As for ASE, I'm not familiar with the architecture of ASE. It's possible that they are not vulnerable to this bug. We notified the ASE developers about this issue and its consequences, but I am not aware of what came of it. For SA/IQ, working around this bug would require significant changes.
