Improper control of a resource through its lifetime in Linux kernel - CVE-2026-89931

Vulnerability identifier: #VU150354

CSH Severity: Low

CVSS v4: 0 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-89931

CWE-ID: CWE-664

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to cause vmcs12 pages to be double-mapped.

The vulnerability exists due to improper state management in KVM nVMX nested VM-Exit handling when emulating a nested VM-Exit. A local user can trigger a nested VM-Exit without the pending request being cleared to cause vmcs12 pages to be double-mapped.

The condition can occur if KVM exits VM-Enter without processing the request before emulating VMLAUNCH or VMRESUME.
