Overview

CVE-2026-74380 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, 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:

gpu: host1x: Fix iommu_map_sgtable() return value check

Commit "iommu: return full error code from iommu_map_sg[_atomic]()"

changed iommu_map_sgtable() to return an ssize_t and negative values

in error cases, rather than a size_t and a zero.

pin_job() also was incorrectly assigning to 'int', which could cause

overflows into negative values.

Update pin_job() to correctly check for errors from iommu_map_sgtable.

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.
