CVE-2022-48765

The CVE-2022-48765 entry corresponds to a Linux kernel issue in KVM LAPIC handling during SET_LAPIC. The accompanying (unpatched) Nessus/OpenVAS notes describe a scenario where rebooting a guest with tsc-deadline mode not exposed can trigger a preemption timer cancellation via apic_update_lvtt(),...

Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the KVM:LAPIC module de-preempting the preemption timer during SETLAPIC...

kernel: KVM: LAPIC: Also cancel preemption timer during SET_LAPIC

A vulnerability was found in the Linux kernel's KVM component related to the LAPIC during the guest reboot process. This issue arises when the SETLAPIC command is issued without exposing the tsc-deadline mode, leading to warnings and potential inconsistencies due to an unhandled preemption timer...
