ثغرة أمنية في مكوّن برمجي — CVE-2026-1681

تؤثر هذه الثغرة الموثقة في zephyrproject zephyr. يوضح سجل NVD أن المشكلة تتمثل في: Issuing an ICMP ping via the `net ping` shell command to a device's own IPv4 address causes the network stack to recursively re-enter the input path on the same system work-queue stack. Because the destination is recognized as a local address, both the echo request and the resulting echo reply are processed inline before the current frame returns. The nested input-path frames exceed the work-queue stack and trigger a stack overflow.
