CVE-2026-1681

net: Stack Overflow with Ping (to own IP Address) via Shell

Published May 12, 2026 CVSS 3.1 · 6.1 Medium EPSS < 1% KEV · Not listed
Description
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.
