CVE-2026-108952 Medium · 4.6 CWE-843 Oct 12, 2026
RT-Thread through 5.3.0 Memory Corruption via USB CDC VCOM Driver
RT-Thread through 5.3.0 contains a memory corruption vulnerability in the legacy USB CDC virtual COM port driver that aliases rx_ringbuffer as a Serial V2 rt_serial_rx_fifo in _function_enable(). A connected USB host configuring the CDC device triggers writes past the ring buffer into struct vcom members and an invalid rt_free() on close, causing denial of service.
