Linux kernel NVMe: race condition in FDP placement ID array initialization
CVE-2026-98153 Published on September 25, 2026
nvme: fix racy access to FDP placement id array
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.
