CVE-2026-63983
A flaw was found in the Linux kernel's network emulator netem component. This vulnerability occurs when netem duplicates a packet and re-enqueues it, leading to a recursive packet duplication loop if multiple netem instances are configured. This uncontrolled recursion can exhaust system resources...
