About this tag
CVE-2024-42134 is a Linux kernel vulnerability in the virtio-pci driver that can cause a guest denial-of-service (DoS) condition. The bug involves a null-pointer dereference in the vp_dev->is_avq field during virtqueue teardown, allowing a local attacker to crash a virtual machine. This issue affects systems using the virtio PCI transport, common in virtualized environments. Patches have been released by the upstream kernel and distributions. Administrators should prioritize updating kernels on both guests and hypervisors to mitigate the risk. The tag covers discussion of the vulnerability, its impact, and remediation steps for affected systems.

    CVE-2024-42134: Linux virtio PCI null pointer triggers guest DoS

    A null-pointer bug in the Linux kernel’s virtio-pci driver — tracked as CVE-2024-42134 — can be triggered when the driver attempts to use an uninitialized pointer (vp_dev->is_avq) while tearing down virtqueues, allowing an attacker with local privileges to crash a guest and produce a...
