A local attacker could use this to cause a denial of service (system crash). (CVE-2019-19227) It was discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle ioctl requests to get emulated CPUID features. An attacker with access to /dev/kvm could use this to cause a denial of service (system crash). (CVE-2019-19332) It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle certain conditions. An attacker could use this to specially craft an ext4 file system that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-19767) Gao Chuan discovered that the SAS Class driver in the Linux kernel contained a race condition that could lead to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-19965) It was discovered that the Datagram Congestion Control Protocol (DCCP) implementation in the Linux kernel did not properly deallocate memory in certain error conditions. An attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-20096) Mitchell Frank discovered that the Wi-Fi implementation in the Linux kernel when used as an access point would send IAPP location updates for stations before client authentication had completed. A physically proximate attacker could use this to cause a denial of service. (CVE-2019-5108) It was discovered that a race condition can lead to a use-after-free while destroying GEM contexts in the i915 driver for the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-7053) It was discovered that the B2C2 FlexCop USB device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15291) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: linux-image-4.15.0-1033-oracle 4.15.0-1033.36 linux-image-4.15.0-1052-gke 4.15.0-1052.55 linux-image-4.15.0-1053-kvm 4.15.0-1053.53 linux-image-4.15.0-1055-raspi2 4.15.0-1055.59 linux-image-4.15.0-1060-aws 4.15.0-1060.62 linux-image-4.15.0-1072-snapdragon 4.15.0-1072.79 linux-image-4.15.0-88-generic 4.15.0-88.88 linux-image-4.15.0-88-generic-lpae 4.15.0-88.88 linux-image-4.15.0-88-lowlatency 4.15.0-88.88 linux-image-aws 4.15.0.1060.61 linux-image-aws-lts-18.04 4.15.0.1060.61 linux-image-generic 4.15.0.88.80 linux-image-generic-lpae 4.15.0.88.80 linux-image-gke 4.15.0.1052.56 linux-image-gke-4.15 4.15.0.1052.56 linux-image-kvm 4.15.0.1053.53 linux-image-lowlatency 4.15.0.88.80 linux-image-oracle 4.15.0.1033.38 linux-image-oracle-lts-18.04 4.15.0.1033.38 linux-image-powerpc-e500mc 4.15.0.88.80 linux-image-powerpc-smp 4.15.0.88.80 linux-image-powerpc64-emb 4.15.0.88.80 linux-image-powerpc64-smp 4.15.0.88.80 linux-image-raspi2 4.15.0.1055.53 linux-image-snapdragon 4.15.0.1072.75 linux-image-virtual 4.15.0.88.80 Ubuntu 16.04 LTS: linux-image-4.15.0-1033-oracle 4.15.0-1033.36~16.04.1 linux-image-4.15.0-1055-gcp 4.15.0-1055.59 linux-image-4.15.0-1060-aws 4.15.0-1060.62~16.04.1 linux-image-4.15.0-1071-azure 4.15.0-1071.76 linux-image-4.15.0-88-generic 4.15.0-88.88~16.04.1 linux-image-4.15.0-88-generic-lpae 4.15.0-88.88~16.04.1 linux-image-4.15.0-88-lowlatency 4.15.0-88.88~16.04.1 linux-image-aws-hwe 4.15.0.1060.60 linux-image-azure 4.15.0.1071.74 linux-image-gcp 4.15.0.1055.69 linux-image-generic-hwe-16.04 4.15.0.88.98 linux-image-generic-lpae-hwe-16.04 4.15.0.88.98 linux-image-gke 4.15.0.1055.69 linux-image-lowlatency-hwe-16.04 4.15.0.88.98 linux-image-oem 4.15.0.88.98 linux-image-oracle 4.15.0.1033.26 linux-image-virtual-hwe-16.04 4.15.0.88.98 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.
