Overview

CVE-2026-46332 is a high-severity vulnerability. It was published on June 9, 2026 and has a CVSS 3.1 base score of 8.0 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.0, 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:

greybus: gb-beagleplay: bound bootloader receive buffering

cc1352_bootloader_rx() appends each serdev chunk into the fixed

rx_buffer before parsing bootloader packets. The helper can keep

leftover bytes between callbacks and may receive multiple packets in one

callback, so a single count value is not constrained by one packet

length.

Check that the incoming chunk fits in the remaining receive buffer space

before memcpy(). If it does not, drop the staged data and consume the

bytes instead of overflowing rx_buffer.

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.
