Remote kernel compromise via unsafe XDP transmission
Published Jan 21, 2025 · Updated Aug 5, 2026
Memory corruption in Linux kernel GVE allows remote attackers to compromise or crash hosts via packets processed by an XDP redirect. gve_xdp_xmit indexes zero XDP queues when no GVE XDP program exists, can dereference a null TX array, and can access freed ring and DMA memory during an unsynchronized close. A GVE interface and victim-configured XDP redirect are required; crafted traffic can disclose or overwrite kernel memory or repeatedly panic the host.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
