CVE-2020-36313
An issue was discovered in the Linux kernel before 5.7. The KVM subsystem allows out-of-range access to memslots after a deletion, aka CID-0774a964ef56. This affects arch/s390/kvm/kvm-s390.c, include/linux/kvmhost.h, and virt/kvm/kvmmain.c...
Denial Of Service
kernel is vulnerable to denial of service. It was found that the kvmvmioctlassigndevice function in the KVM subsystem of a Linux kernel did not check if the user requesting device assignment was privileged or not. A member of the kvm group on the host could assign unused PCI devices, or even...
Denial Of Service (DoS)
kernel is vulnerable to denial of service. A flaw was found in the way the KVM subsystem of a Linux kernel handled PIT Programmable Interval Timer IRQs interrupt requests when there was no virtual interrupt controller set up. A malicious user in the kvm group on the host could force this situatio...
CVE-2018-19406
A NULL pointer dereference security flaw was found in the Linux kernel in kvmpvsendipi in arch/x86/kvm/lapic.c. This allows local users with certain privileges to cause a denial of service via a crafted system call to the KVM subsystem...
CVE-2018-19407
A NULL pointer dereference security flaw was found in the Linux kernel in the vcpuscanioapic function in arch/x86/kvm/x86.c. This allows local users with certain privileges to cause a denial of service via a crafted system call to the KVM subsystem...
F5 Networks BIG-IP : Linux kernel KVM subsystem vulnerability (K11186236)

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities : - It was found that the parserockridgeinodeinternal function of the Linux kernel's ISOFS implementation did not correctl...
Privilege Escalation
The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way Linux kernel's Transparent Huge Pages THP implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent...
Amazon Linux AMI : kernel (ALAS-2018-1133)
A security flaw was found in the Linux kernel in a way that the cleancache subsystem clears an inode after the final file truncation removal. The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one.CVE-2018-16862 An issue wa...
