CVE-2017-7518

A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flagTF bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exceptionDB being raised in the guest stack. A user/process inside a guest could use this flaw to...

CVE-2017-7518

CVE-2017-7518: In the Linux kernel before 4.12, the KVM module mishandles the trap-flag TF in EFLAGS during syscall emulation, causing a debug exception (#DB) on the guest stack. This could allow a user/process inside a guest to escalate privileges within the guest (Linux guests only; host kernel...

Design/Logic Flaw

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-cp...

CVE-2018-10901

CVE-2018-10901 affects the Linux kernel’s KVM virtualization subsystem. The VMX path fails to restore the guest GDT.LIMIT to the host value, setting it to 64KB instead. This can allow a host userspace process to corrupt GDT entries (notably per-cpu variables), enabling local privilege escalation....
