0 CVE-2026-12632 is a vulnerability in Zephyr's Precision Time Protocol (PTP) receive handler where an out-of-bounds read occurs due to improper indexing of a message size table. This flaw allows an attacker on the same network link to cause a denial of service by triggering a crash. The vulnerability arises because the message type extracted from network packets is not properly bounded before indexing an array, leading to memory corruption risks. The issue affects Zephyr versions from 3.7.0 up to but not including 4.4.2. A fix is available that rejects out-of-range message types before indexing.
