Overview

CVE-2026-23132 is a medium-severity vulnerability. It was published on February 14, 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:

drm/bridge: synopsys: dw-dp: fix error paths of dw_dp_bind

Fix several issues in dw_dp_bind() error handling:

1. Missing return after drm_bridge_attach() failure - the function

continued execution instead of returning an error.

2. Resource leak: drm_dp_aux_register() is not a devm function, so

drm_dp_aux_unregister() must be called on all error paths after

aux registration succeeds. This affects errors from:

- drm_bridge_attach()

- phy_init()

- devm_add_action_or_reset()

- platform_get_irq()

- devm_request_threaded_irq()

3. Bug fix: platform_get_irq() returns the IRQ number or a negative

error code, but the error path was returning ERR_PTR(ret) instead

of ERR_PTR(dp->irq).

Use a goto label for cleanup to ensure consistent error handling.

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.
