Overview

CVE-2026-43397 is a medium-severity vulnerability. It was published on May 8, 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: samsung-dsim: Fix memory leak in error path

In samsung_dsim_host_attach(), drm_bridge_add() is called to add the

bridge. However, if samsung_dsim_register_te_irq() or

pdata->host_ops->attach() fails afterwards, the function returns

without removing the bridge, causing a memory leak.

Fix this by adding proper error handling with goto labels to ensure

drm_bridge_remove() is called in all error paths. Also ensure that

samsung_dsim_unregister_te_irq() is called if the attach operation

fails after the TE IRQ has been registered.

samsung_dsim_unregister_te_irq() function is moved without changes

to be before samsung_dsim_host_attach() to avoid forward declaration.

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.
