7.8 · HIGHOverview
CVE-2025-71157 is a high-severity vulnerability affecting linux linux_kernel. It was published on January 23, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, 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: always drop device refcount in ib_del_sub_device_and_put()
Since nldev_deldev() (introduced by commit 060c642b2ab8 ("RDMA/nldev: Add
support to add/delete a sub IB device through netlink") grabs a reference
using ib_device_get_by_index() before calling ib_del_sub_device_and_put(),
we need to drop that reference before returning -EOPNOTSUPP error.
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.
