Overview

CVE-2026-90316 is a high-severity vulnerability. It was published on September 17, 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:

drm/omap: dsi: Do not copy isr table

To be able to unregister stuff from isrs, the corresponding table was

copied. Nobody seems to unregister stuff that way, so it does not help.

But there are stack-allocated objects passed to these isrs giving chances

of UAF of these objects if irqs are unregistered while they are handled,

so better do not copy that table.

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.
