Status: Precise Development Kernel

We have uploaded the 3.2.0-3.8 Ubuntu kernel which is based on latest upstream v3.2-rc4 kernel. The 3.2.0-3.8 upload also resolved the remaining armhf build issues. We are still witholding the patches to drop the i386 non-pae flavor until after the Tech Board discussion regarding the issue on Mon Dec 12.
Important Upcoming Dates:

• Thurs Feb 2 – Alpha 2 (~8 weeks)

Status: CVE’s

=== CVE Metrics ===

Currently open CVEs for each supported branch:

We gained a couple of new CVEs this week and closed out the same number
so the overall stats remain static. We only have fixes for two of the
remaining CVEs.

== 2011-11-29 (weekly) ==

=== CVE Metrics ===

Currently open CVEs for each supported branch:

We gained yet another 5 CVEs this week. We closed out a couple. Two of
the new CVEs await upstream fixes.
