CVE-2025-38553
CVE-2025-38553 affects the Linux kernel (net/sched). The issue concerns the duplication logic for netem instances in a qdisc tree, where the existing netem_enqueue handling can misbehave when a netem coexists with others, potentially causing a soft lockup or OOM loop in netem_dequeue. The connect...
