Ubuntu: 4227-1 Moderate: Kernel Memory Exhaustion And Buffer Overflows

The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: linux-image-4.15.0-1031-oracle 4.15.0-1031.34 linux-image-4.15.0-1050-gke 4.15.0-1050.53 linux-image-4.15.0-1052-kvm 4.15.0-1052.52 linux-image-4.15.0-1053-raspi2 4.15.0-1053.57 linux-image-4.15.0-1057-aws 4.15.0-1057.59 linux-image-4.15.0-1066-oem 4.15.0-1066.76 linux-image-4.15.0-1070-snapdragon 4.15.0-1070.77 linux-image-4.15.0-74-generic 4.15.0-74.84 linux-image-4.15.0-74-generic-lpae 4.15.0-74.84 linux-image-4.15.0-74-lowlatency 4.15.0-74.84 linux-image-aws 4.15.0.1057.58 linux-image-aws-lts-18.04 4.15.0.1057.58 linux-image-generic 4.15.0.74.76 linux-image-generic-lpae 4.15.0.74.76 linux-image-gke 4.15.0.1050.53 linux-image-gke-4.15 4.15.0.1050.53 linux-image-kvm 4.15.0.1052.52 linux-image-lowlatency 4.15.0.74.76 linux-image-oem 4.15.0.1066.70 linux-image-oracle 4.15.0.1031.36 linux-image-oracle-lts-18.04 4.15.0.1031.36 linux-image-powerpc-e500mc 4.15.0.74.76 linux-image-powerpc-smp 4.15.0.74.76 linux-image-powerpc64-emb 4.15.0.74.76 linux-image-powerpc64-smp 4.15.0.74.76 linux-image-raspi2 4.15.0.1053.51 linux-image-snapdragon 4.15.0.1070.73 linux-image-virtual 4.15.0.74.76 Ubuntu 16.04 LTS: linux-image-4.15.0-1031-oracle 4.15.0-1031.34~16.04.1 linux-image-4.15.0-1052-gcp 4.15.0-1052.56 linux-image-4.15.0-1057-aws 4.15.0-1057.59~16.04.1 linux-image-4.15.0-1066-azure 4.15.0-1066.71 linux-image-4.15.0-74-generic 4.15.0-74.83~16.04.1 linux-image-4.15.0-74-generic-lpae 4.15.0-74.83~16.04.1 linux-image-4.15.0-74-lowlatency 4.15.0-74.83~16.04.1 linux-image-aws-hwe 4.15.0.1057.57 linux-image-azure 4.15.0.1066.69 linux-image-azure-edge 4.15.0.1066.69 linux-image-gcp 4.15.0.1052.66 linux-image-generic-hwe-16.04 4.15.0.74.94 linux-image-generic-lpae-hwe-16.04 4.15.0.74.94 linux-image-gke 4.15.0.1052.66 linux-image-lowlatency-hwe-16.04 4.15.0.74.94 linux-image-oem 4.15.0.74.94 linux-image-oracle 4.15.0.1031.24 linux-image-virtual-hwe-16.04 4.15.0.74.94 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
