AZL-70468 CVE-2022-50224 affecting package kernel 5.15.200.1-1
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-2022-50228
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-2022-50227
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
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 ...
