Out-of-bounds write in LR11xx Transceiver
An out-of-bounds write vulnerability in the SPI host command interface of Semtech's LR11xx transceiver firmware where a crafted SPI host command with an oversized length field can cause the firmware to write up to 254 arbitrary bytes past the bounds of an internal, non-persistent memory buffer. Exploitation requires physical access to the device and logical access to the SPI bus.
