I guess you are talking about CVE-2016–5195 here. Please correct me if mistaken.

If 4.4.8 gets patched you will find a new revision (i.e. 4.4.8-r2). This is quite standard Gentoo policy, if a package is modifed after publication (for example by backporting patches) the revision of the packet has to be increased so that users will be able to use these when updating. The only exceptions I know of are the -9999 packages for bleeding edge trunks and some very minor changes (think for example of a fix in the build system or a minor documentation fix) which a fix for CVE-2016–5195 clearly wouldn't be. You can read more on the Gentoo project revision policy for ebuilds at

According to CVE-2016-5195 has been around since 2.6.22 so 4.4.8-r1 is not patched and is needed to protect against this issue, as for whether there will or not be a backported patch you should ask blueness but my guess is that there won't be one unless somebody provides such backported patch to blueness. I'm CCing the Gentoo Hardened user list as other users may be able to provide more and better input on this. Sincerely, Francisco Blas Izquierdo Riera (klondike)
