No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： nvmet：修复 nvmet_execute_identify_ns_zns() 中的空指针解引用 当主机发起带有 CNS 05h（I/O 命令集特定的 Identify Namespace）和 CSI 02h（ZNS）的 Identify 命令，且目标是文件后端命名空间时，nvmet_execute_identify_ns_zns() 会对 req->ns->bdev 调用 bdev_is_zoned()。由于文件后端命名空间没有块设备，req->ns->bdev 为 N

Vulnerability Title
nvmet: fix NULL pointer dereference in nvmet_execute_identify_ns_zns()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: nvmet: fix NULL pointer dereference in nvmet_execute_identify_ns_zns() When a host issues an Identify command with CNS 05h (I/O Command Set specific Identify Namespace) and CSI 02h (ZNS) targeting a file-backed namespace, nvmet_execute_identify_ns_zns() calls bdev_is_zoned() on req->ns->bdev. A file-backed namespace has no block device, so req->ns->bdev is NULL and bdev_is_zoned() dereferences it, oopsing. The I/O command set is selected by the host-supplied CSI field and the command is routed here whenever CONFIG_BLK_DEV_ZONED is enabled, independent of the namespace backing type, so any file-backed namespace is exposed. Reject the command with Invalid Field when the namespace is not backed by a block device.
