CVE-2022-49932
In the Linux kernel, the following vulnerability has been resolved: KVM: VMX: Do all initialization before exposing /dev/kvm to userspace Call kvminit only after all setup is complete, as kvminit exposes /dev/kvm to userspace and thus allows userspace to create VMs and call other ioctls. E.g. KVM...

CVE-2022-49932
CVE-2022-49932 affects the Linux kernel KVM/vMX path where /dev/kvm is exposed before VMX initialization is complete. The EulerOS advisories (EulerOS-SA-2025-2464/2483, EulerOS-SA-2025-2436/2447) flag this issue as part of kernel fixes and describe the root cause as incomplete initialization prio...

CVE-2022-49884
In the Linux kernel, the following vulnerability has been resolved: KVM: Initialize gfntopfncache locks in dedicated helper Move the gfntopfncache lock initialization to another helper and call the new helper during VM/vCPU creation. There are race conditions possible due to kvmgfntopfncacheinit'...
CVE-2022-49882
In the Linux kernel, the following vulnerability has been resolved: KVM: Reject attempts to consume or refresh inactive gfntopfncache Reject kvmgpccheck and kvmgpcrefresh if the cache is inactive. Not checking the active flag during refresh is particularly egregious, as KVM can end up with a vali...
CVE-2022-49883
In the Linux kernel, the following vulnerability has been resolved: KVM: x86: smm: number of GPRs in the SMRAM image depends on the image format On 64 bit host, if the guest doesn't have X86FEATURELM, KVM will access 16 gprs to 32-bit smram image, causing out-ouf-bound ram access. On 32 bit host,...

CVE-2022-49884
CVE-2022-49884 concerns the Linux kernel KVM, where the gfn_to_pfn_cache locks could race during VM/vCPU creation. The issue is addressed by moving the gfn_to_pfn_cache lock initialization to a dedicated helper and calling it during VM/vCPU creation, reducing race conditions that could corrupt th...

CVE-2022-49882
CVE-2022-49882 concerns the Linux kernel KVM gfn_to_pfn_cache handling. The issue arises when the cache is inactive but refreshed without verifying the active flag, potentially leaving a valid but inactive cache and enabling use-after-free scenarios (e.g., dereferencing NULL kernel pointers or mi...
