Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The Linux kernel NVMe driver (nvme) is affected from 4.15 until the fixed stable releases. In an error path during namespace allocation, a namespace can be freed while a concurrent multipath reader still holds a reference to it. The source gives few details on what an attacker needs. Upgrade to Linux 5.10.273, 5.15.224, 6.1.191, 6.6.160, or a later stable release in the same series.
