Hi, Daniel & Greg
This patch (979d63d50c0c bpf: prevent out of bounds speculation on pointer arithmetic) was assigned a CVE (CVE-2019-7308) with a high score:
CVSS v3.0 Severity and Metrics: Base Score: 9.8 CRITICAL
And this patch is not in stable-4.4, would you please backport this patch to 4.4?
For a bit more context, it's also not in 4.14.y, 4.9.y, or 4.4.y. I found a backported series for 4.4.y in the SLES kernel tree that I could try to import here if it really is a big deal.
I'm sorry that I did not find them. I only know the SLES kernel tree at: https://github.com/openSUSE/kernel. Is there another place for the SLES kernel tree?
That's the tree you want, look at the SLES branches. I see the patches backported to the SLE12-SP4 branch already, so that is hopefully a working set of patches for 4.4.y.
I checked the SLE12-SP4 branch and the kernel version is 4.12. There is still a lot of conflicts even with 4.14.y. So it's hard to backport to 4.4.y. I will try to solve the conflicts with 4.14.y but I'm not sure if I can solve all the conflicts and finish this job.
thanks,
