CVE-2026-98153 nvme: fix racy access to FDP placement id array

What is CVE-2026-98153?

CVE-2026-98153 is a medium-severity vulnerability in Linux kernel, published on 25 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

In the Linux kernel, the following vulnerability has been resolved:

nvme: fix racy access to FDP placement id array

nvme_query_fdp_info() is called per-path and therefore prone to races.

It populates head->nr_plids/head->plids for fdp registration. But nothing protects that pair from concurrent access - two paths scanning the same namespace can race to populate it.

Avoid the race by moving this initialization work to nvme_alloc_ns_head() which is called once per shared namespace.

Weakness: CWE-362
