CVE-2022-49154

The CVE-2022-49154 entry is validated by connected advisories describing a Linux kernel KVM SVM issue: an out-of-bounds guest IRQ in svm_update_pi_irte() could crash when guest_irq comes via KVM_IRQFD. The root cause is an out-of-bounds access that could trigger a crash; the mitigation is a kerne...

CVE-2021-47639

CVE-2021-47639 affects the Linux kernel KVM x86/mmu code. The issue arises when unmapping a guest frame number (gfn) range in the TDP MMU: both valid and invalid SPTE roots can be zapped, but invalid roots aren’t consistently cleared in mmu_notifier paths. This can leave references to freed pages...
