CVE-2026-46332
8.0 · HIGHOverview
CVE-2026-46332 is a high-severity vulnerability affecting linux linux_kernel. 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 and patches from linux. Update linux_kernel to the latest patched version. 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.
