CVE-2019-19332 – Kernel: kvm: OOB memory write via kvm_dev_ioctl_get_cpuid
https://notcve.org/view.php?id=CVE-2019-19332
09 Jan 2020 — An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use this flaw to crash the system, resulting in a denial of service.

CVE-2019-5108 – kernel: triggering AP to send IAPP location updates for stations before the required authentication process has completed can lead to DoS
https://notcve.org/view.php?id=CVE-2019-5108
23 Dec 2019 — An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure.

22 Dec 2019 — kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1.
