CVE-2026-10644: bounds in zephyrproject zephyrCVE-2026-10644 0 CVE-2026-10644 is a medium severity vulnerability in the Microchip SERCOM-G1 UART driver of the Zephyr project affecting the PIC32CM-JH SoC family. It involves an out-of-bounds write in the asynchronous DMA receive path when a one-byte receive buffer is used with async UART enabled. This causes a single-byte memory corruption adjacent to the RX buffer, potentially leading to a crash or denial of service. The issue exists in Zephyr versions 4.4.0 up to but not including 4.5.0. The fix changes the handling of one-byte buffers to avoid DMA and properly reads the first byte with the CPU.
