description

Eclipse ThreadX NetX Duo 6.4.5.202504 through 6.5.2.202603a is affected when built with IPv6 path MTU discovery enabled. A network-based attacker may halt network processing by exhausting destination-table capacity, provided the target faults on null-address access.

mitigation

Upgrade NetX Duo to 6.5.2.202603b or later.
