CVE-2026-46332: Linux

Описание

Оригинално описание

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.
