Xen Security Advisory 522 v1 (CVE-2026-98375) - Linux xen-netfront: backend can crash guest via malformed RX packets
Xen published security advisory CVE-2026-98375 (XSA-522) addressing a denial of service vulnerability in the Linux xen-netfront driver. A malicious network backend can craft malformed receive packets that trigger a crash in the guest operating system when split across multiple slots with an undersized first slot.
Why it matters: Virtual machine operators using Linux guests with xen-netfront should apply the patch immediately, as an untrusted or compromised network backend can crash guest instances.
