Exploitation
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，以下漏洞已得到修复： nvme-multipath：仅在获取区域（zone）信息后，才设置 BLK_FEAT_ZONED 标志。 此前，命名空间头（namespace head）在分配时仅依据命令集标识符（command set identifier）被标记为区域设备。如果区域信息查询返回的区域大小为 0，则路径命名空间（path namespace）会在未设置区域限制的情况下注册，而命名空间头仍会宣称支持区域功能，但区域大小为 0。此时，若尝试报告区域或向命名空间头写入数据，将导致按 il

Vulnerability Title
nvme-multipath: set BLK_FEAT_ZONED only after the zone info is known
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: nvme-multipath: set BLK_FEAT_ZONED only after the zone info is known The namespace head is marked zoned at allocation time based only on the command set identifier. If the zone info query reports a zero zone size, the path namespace is registered without zoned limits while the head still advertises the zoned capability with a zone size of zero, and reporting zones or writing to the head then shifts by ilog2(0). Drop the zoned feature from the head allocation and let the head limits refresh stack it in from the path namespace instead.
