CVE-2026-10678 NULL-pointer / out-of-bounds write in Zephyr MCTP I2C+GPIO target binding driven by an unauthenticated I2C controller

The MCTP-over-I2C+GPIO target binding in Zephyr subsys/pmci/mctp/mctpi2cgpiotarget.c processes pseudo-register writes from an I2C bus master byte-by-byte in mctpi2cgpiotargetwritereceived without validating the order or the receive buffer. In the affected versions the MCTPI2CGPIORXMSGADDR data...

CVE-2026-10678

The CVE-2026-10678 issue affects Zephyr’s MCTP over I2C+GPIO target binding (mctp_i2c_gpio_target.c). It processes I2C bus master writes byte-by-byte without validating the receive buffer, dereferencing b->rx_pkt to write data for data registers (MCTP_I2C_GPIO_RX_MSG_ADDR) before the receive b...

CVE-2026-64205

A flaw was found in the Linux kernel's i2c-i801 driver. This vulnerability allows a local attacker to trigger a hardware state machine corruption during error handling.
