CVE-2026-52997

The CVE-2026-52997 issue affects the Linux kernel’s net/sched sch_dualpi2 qdisc. The root cause was that dualpi2_change() could attempt to dequeue from the C-queue even when it was empty while packets resided in the L-queue, leading to a NULL skb dereference during limit/memlimit enforcement. The...
