CVE-2026-1681 net: Stack Overflow with Ping (to own IP Address) via Shell

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...
