CVE-2026-23090 is a medium-severity vulnerability. It was published on February 4, 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:

slimbus: core: fix device reference leak on report present

Slimbus devices can be allocated dynamically upon reception of

report-present messages.

Make sure to drop the reference taken when looking up already registered

devices.

Note that this requires taking an extra reference in case the device has

not yet been registered and has to be allocated.

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.
