CVE-2026-98153

Summary

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.
