CVE-2026-12634: bounds in zephyrproject zephyrCVE-2026-12634 0 CVE-2026-12634 is a medium severity vulnerability in the Zephyr project's settings subsystem where a fixed-size stack buffer is used to read setting-name entries. An attacker with the ability to write directly to the flash backing the settings partition can craft oversized entries that cause a single out-of-bounds NUL byte write past the buffer. This can lead to a crash or denial of service due to limited stack corruption. The vulnerability is not exploitable remotely via the normal settings API and does not impact confidentiality. The issue affects Zephyr versions 2.0.0 and all versions from 2.0.0 up to but not including 4.5.0. No official patch or remediation level has been confirmed yet.
