Overview

CVE-2026-46077 is a medium-severity vulnerability. It was published on May 27, 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:

crypto: atmel-tdes - fix DMA sync direction

Before DMA output is consumed by the CPU, ->dma_addr_out must be synced

with dma_sync_single_for_cpu() instead of dma_sync_single_for_device().

Using the wrong direction can return stale cache data on non-coherent

platforms.

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.
