FKIE_CVE-2022-50228
Vulnerability from fkie_nvd - Published: 2025-06-18 11:15 - Updated: 2026-06-17 05:23
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: Don't BUG if userspace injects an interrupt with GIF=0
Don't BUG/WARN on interrupt injection due to GIF being cleared,
since it's trivial for userspace to force the situation via
KVM_SET_VCPU_EVENTS (even if having at least a WARN there would be correct
for KVM internally generated injections).
