| CVE-2018-12904 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | N/A |
| In arch/x86/kvm/vmx.c in the Linux kernel before 4.17.2, when nested virtualization is used, local attackers could cause L1 KVM guests to VMEXIT, potentially allowing privilege escalations and denial of service attacks due to lack of checking of CPL. | ||||
| CVE-2018-10901 | 2 Linux, Redhat | 9 Linux Kernel, Enterprise Linux, Enterprise Linux Desktop and 6 more | 2024-11-21 | 7.8 High |
| A flaw was found in Linux kernel's KVM virtualization subsystem. The VMX code does not restore the GDT.LIMIT to the previous host value, but instead sets it to 64KB. With a corrupted GDT limit a host's userspace code has an ability to place malicious entries in the GDT, particularly to the per-cpu variables. An attacker can use this to escalate their privileges. | ||||
| CVE-2018-10853 | 4 Canonical, Debian, Linux and 1 more | 9 Ubuntu Linux, Debian Linux, Linux Kernel and 6 more | 2024-11-21 | N/A |
| A flaw was found in the way Linux kernel KVM hypervisor before 4.18 emulated instructions such as sgdt/sidt/fxsave/fxrstor. It did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could use this flaw to potentially escalate privileges inside guest. | ||||
| CVE-2017-7518 | 4 Canonical, Debian, Linux and 1 more | 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more | 2024-11-21 | N/A |
| A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Linux guests are not affected by this. | ||||
