Overview

CVE-2026-98252 is a high-severity vulnerability. It was published on October 6, 2026 and has a CVSS 3.1 base score of 7.0 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.0, rated HIGH. 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:

RDMA/core: fix refcount bug in iwpm_get_nlmsg_request()

iwpm_get_nlmsg_request() initializes refcount _after_ list_add_tail()

making it accessible to global list where another CPU can kref_get()

on nlmsg_request causing a refcount "addition on 0" bug. Fix this

by initializing kref _before_ list_add_tail() so refcount for

nlmsg_request can be incremented/decremented normally. In addition,

also initialize every field before list_add_tail().

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
