CVE-2025-21702

The CVE CVE-2025-21702 concerns a bug in Linux kernel pfifo_tail_enqueue where, when sch->limit == 0, a path can cause qlen to be increased to one even if a preceding drop would have kept it at zero. This leads to a mismatch where a parent qlen no longer equals the sum of its children’s qlen, ...
