CVE-2022-50228

CVE-2022-50228 is a Linux kernel vulnerability affecting KVM on x86 with SVM. The issue occurs when userspace can inject an interrupt with GIF=0, which can trigger a kernel BUG (fatal crash) in arch/x86/kvm/svm/svm.c. The provided descriptions explicitly show a kernel BUG at svm_inject_irq and an...
