In the Linux kernel, the following vulnerability has been resolved: KVM: VMX: Do _all_ initialization before exposing /dev/kvm to userspace Call kvm_init() only after _all_ setup is complete, as kvm_init() exposes /dev/kvm to userspace and thus allows userspace to create VMs (and call other ioctls). E.g. KVM will encounter a NULL pointer when attempting to add a vCPU to the per-CPU loaded_vmcss_on_cpu list if userspace is able to create a VM before vmx_init() configures said list.

Tenable has extracted the preceding description block directly from the EulerOS kernel security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - KVM: VMX: Do _all_ initialization before exposing /dev/kvm to userspace Call kvm_init() only after _all_     setup is complete, as kvm_init() exposes /dev/kvm to userspace and thus allows userspace to create VMs     (and call other ioctls). E.g. KVM will encounter a NULL pointer when attempting to add a vCPU to the per-     CPU loaded_vmcss_on_cpu list if userspace is able to create a VM before vmx_init() configures said list.

Note that Nessus relies on the presence of the package as reported by the vendor.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-148 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    KVM: VMX: Do _all_ initialization before exposing /dev/kvm to userspace (CVE-2022-49932)

    A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve     local privilege escalation.

    The perf_group_detach function did not check the event's siblings' attach_state before calling     add_event_to_groups(), but remove_on_exec made it possible to call list_del_event() on before detaching     from their group, making it possible to use a dangling pointer causing a use-after-free vulnerability.

    We recommend upgrading past commit fd0815f632c24878e325821943edccc7fde947a2. (CVE-2023-2235)

    do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference). (CVE-2023-28466)

    An issue was discovered in arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x86_64     lacks consistency checks for CR0 and CR4. (CVE-2023-30456)
