0 CVE-2026-19737 is a memory-safety vulnerability in the Zephyr project's i2s_esp32 driver affecting versions from 4.4.0 up to but not including 4.5.0. The flaw arises because the driver does not properly check stream pointers for certain I2S directions, leading to a NULL pointer dereference when a user-mode thread triggers an unwired direction. This results in a kernel-mode read from address zero, causing a system halt and denial of service. The vulnerability impacts availability but does not allow information disclosure or code execution. The issue is fixed by adding pointer checks and returning an error for unsupported directions. Join the discussion | CVE Database V5 | 10/11/2026, 17:15:01 UTC Added: 10/11/2026, 17:34:03 UTC |
