Title
Out-of-bounds write in LR11xx Transceiver
Summary
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.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
