Advisory:

This update is based on the upstream 4.4.30 kernel and fixes atleast theese
security issues:

The filesystem implementation in the Linux kernel through 4.8.2 preserves
the setgid bit during a setxattr call, which allows local users to gain
group privileges by leveraging the existence of a setgid program with
restrictions on execute permissions (CVE-2016-7097).

Stack-based buffer overflow in the brcmf_cfg80211_start_ap function in 
drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux
kernel before 4.7.5 allows local users to cause a denial of service
(system crash) or possibly have unspecified other impact via a long SSID
Information Element in a command to a Netlink socket (CVE-2016-8658).

The IP stack in the Linux kernel before 4.6 allows remote attackers to
cause a denial of service (stack consumption and panic) or possibly have
unspecified other impact by triggering use of the GRO path for packets with
tunnel stacking, as demonstrated by interleaved IPv4 headers and GRE headers,
a related issue to CVE-2016-7039 (CVE-2016-8666).

The fix for CVE-2016-7039 added in MGASA-2016-0347 has been updated to the
final version merged upstream.

This update also resolves a regression where amdgpu and radeon users would
not get any display when using displayport (upstream regression introduced
in 4.4.21, mga#19707)

For other upstream fixes in this update, read the referenced changelogs.

On real hardware:

AMD Athlon X2 7750, nvidia graphics using 340 driver, 64-bit server kernel.
Intel i3, Intel graphics, Intel wifi, 64-bit desktop kernel.

Both systems already had VirtualBox 5.1.8 installed, so the kernel modules were build locally by dkms.

Both systems function normally. No regressions noted. Thunderbird, Firefox, VLC, VirtualBox all work. Mageia VirtualBox guests still need "nomodeset" option to boot.

Have used this intermittently (because of needing to remember to select it specifically from the Grub2 'advanced' boot menu) without visible problems.
For me OK.

Running fine for me on an i586 Dell laptop and a couple different x86_64 workstations.  I think this can be validated.

Thank you David for the 'OK'. OK'd both architectures, validated, advisory uploaded.

Re Advisory: I first commited this with just 'kernel' SRPM, but have added the others from Comment 0. Puzzled by the version differences (SRPM & derived packages) for the 3 'kmod' SRPMs.
