Technical details
The vulnerability is an out-of-bounds read in libXi's XListInputDevices() function that occurs when parsing device names from the X server response. The vulnerable code does not properly validate buffer boundaries before reading name length values and copying device names, allowing a malicious X server to trigger memory access beyond allocated buffers. The fix adds explicit end-of-buffer checks before each memory access operation.
