Security readout for executives and security teams
Plain-English summary
CVE-2024-53092 is a Linux kernel bug in virtio PCI cleanup. On affected systems, a local low-privileged user could trigger a kernel NULL pointer crash path, causing a denial of service. The sources do not indicate data theft, remote compromise, or active exploitation.
Executive priority
Treat as a moderate availability risk. Patch during the next normal kernel maintenance cycle, faster for multi-tenant or shared systems with local user access.
Technical view
The virtio_pci driver cleaned admin virtqueue resources using the wrong virtio_pci_vq_info pointer. The admin queue info lives in vp_dev->admin_vq.info, not vp_dev->vqs[]. During reset or device removal, this can dereference NULL and crash the kernel.
Likely exposure
Exposure is most relevant to Linux systems running affected 6.11/6.12-era kernels with virtio PCI devices, commonly in virtualized environments. Exact exposure depends on distro backports, kernel configuration, and whether the relevant virtio drivers are present.
Exploitation context
The CVSS vector is local, low complexity, low privileges, no user interaction, with high availability impact. The bundle marks KEV as false, and no provided source states active exploitation.
Researcher notes
The root issue is CWE-476 NULL pointer dereference in admin virtqueue cleanup. Analysis should focus on kernel version provenance, distro backport status, and whether virtio PCI devices are available. The provided sources do not establish confidentiality or integrity impact.
Mitigation direction
- Apply a kernel or distro update containing the referenced stable fixes.
- Check Linux distribution advisories for backported fixes and affected package versions.
- Prioritize systems where untrusted users have local shell or workload execution access.
- Reduce unnecessary local user access on affected shared Linux systems.
- Schedule reboots where required for patched kernels to take effect.
Validation and detection
- Inventory Linux kernel versions against affected 6.11/6.12-era releases.
- Confirm whether virtio_pci or related virtio drivers are loaded.
- Verify the running kernel includes the referenced stable commits or distro backport.
- Review kernel logs for virtio_pci NULL pointer dereference crashes.
- Track remediation through normal kernel package and reboot evidence.
