CVE-2023-6356: Kernel: null pointer dereference in nvmet_tcp_build_iovec

First published: Mon Dec 11 2023(Updated: )

A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver and causing kernel panic and a denial of service.
