Overview

CVE-2026-53159 is a high-severity vulnerability. It was published on June 25, 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:

misc: fastrpc: fix DMA address corruption due to find_vma misuse

fastrpc_get_args() uses find_vma() to look up the VMA for a user-provided

pointer and compute a DMA address offset. When the address falls in a gap

before the returned VMA, (ptr & PAGE_MASK) - vma->vm_start underflows,

corrupting the DMA address sent to the DSP.

Replace find_vma() with vma_lookup(), which returns NULL when the address

is not contained within any VMA.

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.
