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-pci：在探测（probe）失败时释放描述符池 每个 NUMA 节点的描述符 DMA 池是在 中，当管理标签集（admin tag set）被分配后，以懒加载方式创建的。这些池仅在 中通过 被销毁。然而，如果在管理标签集分配之后发生任何探测失败，错误处理会经过 标签和 ，而这两个路径均未释放描述符池，从而导致 对象发生内存泄漏。 修复方案是在 错误路径中释放描述符池。注意，不能将该释放操作添加到 中，因为这样会在正常的拆除（teardown）路径中与 中的释放

Vulnerability Title
nvme-pci: release descriptor pools on probe failure
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: release descriptor pools on probe failure
The per-NUMA-node descriptor DMA pools are created lazily from
nvme_init_hctx_common() once the admin tag set is allocated, but they are
only destroyed in nvme_remove() via nvme_release_descriptor_pools(). Any
probe failure after the admin tag set has been allocated unwinds through
the out_disable label and nvme_pci_free_ctrl(), neither of which releases
the pools, leaking the dma_pool objects.
Release the descriptor pools in the out_disable error path. It must not
be added to nvme_pci_free_ctrl(), as that would double-free against
nvme_remove() on the normal teardown path.
