Overview

CVE-2026-23285 is a medium-severity vulnerability. It was published on March 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:

drbd: fix null-pointer dereference on local read error

In drbd_request_endio(), READ_COMPLETED_WITH_ERROR is passed to

__req_mod() with a NULL peer_device:

__req_mod(req, what, NULL, &m);

The READ_COMPLETED_WITH_ERROR handler then unconditionally passes this

NULL peer_device to drbd_set_out_of_sync(), which dereferences it,

causing a null-pointer dereference.

Fix this by obtaining the peer_device via first_peer_device(device),

matching how drbd_req_destroy() handles the same situation.

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.
