Overview

CVE-2026-98153 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 25, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
