0 CVE-2026-79976 is a memory-safety vulnerability in the Zephyr project's MCTP-over-I2C+GPIO target binding. It arises because the selected register and data-phase flag are not cleared upon an I2C STOP condition, leading to stale state and potential NULL pointer dereferences. This can cause a fatal exception and device reset or halt, resulting in denial of service. The issue affects builds with the experimental CONFIG_MCTP subsystem enabled and CONFIG_MCTP_I2C_GPIO_TARGET set to yes. No confidentiality or integrity breach occurs, and no attacker-controlled data is written. Join the discussion | CVE Database V5 | 10/21/2026, 18:19:34 UTC Added: 10/21/2026, 18:31:45 UTC |
