UBUNTU-CVE-2022-50227

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/xen: Initialize Xen timer only once Add a check for existing xen timers before initializing a new one. Currently kvmxeninittimer is called on every KVMXENVCPUATTRTYPETIMER, which is causing the following ODEBUG crash whe...

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...

CVE-2022-50228 KVM: SVM: Don't BUG if userspace injects an interrupt with GIF=0

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 KVMSETVCPUEVENTS even if having at least...

CVE-2022-50227

CVE-2022-50227 affects the Linux kernel (KVM Xen timer) and is resolved by only initializing the Xen timer once. The root cause is that kvm_xen_init_timer() was invoked for every KVM_XEN_VCPU_ATTR_TYPE_TIMER, risking an ODEBUG crash when vcpu->arch.xen.timer is already set. The fix adds a chec...

CVE-2022-50224 KVM: x86/mmu: Treat NX as a valid SPTE bit for NPT

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Treat NX as a valid SPTE bit for NPT Treat the NX bit as valid when using NPT, as KVM will set the NX bit when the NX huge page mitigation is enabled mindblowing and trigger the WARN that fires on reserved SPTE bits...

CVE-2022-50224

CVE-2022-50224 is a Linux kernel/KVM issue where NX is treated as a valid SPTE bit for NPT, enabling a mismatch that can trigger a WARN when reserved SPTE bits are set. Concrete details come from the Linux kernel KVM/mmu path, including a traceback and a mitigation involving NX handling when the ...
