Overview

CVE-2026-72146 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 8.4 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.4, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: sh: rz-dmac: Move interrupt request after everything is set up

Once the interrupt is requested, the interrupt handler may run immediately.

Since the IRQ handler can access channel->ch_base, which is initialized

only after requesting the IRQ, this may lead to invalid memory access.

Likewise, the IRQ thread may access uninitialized data (the ld_free,

ld_queue, and ld_active lists), which may also lead to issues.

Request the interrupts only after everything is set up. To keep the error

path simpler, use dmam_alloc_coherent() instead of dma_alloc_coherent().

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.
