CVE-2026-99144
The Linux kernel contains a use-after-free vulnerability within the sched_ext component. The issue occurs because a deferred reenqueue can read a freed user DSQ (Dispatcher Status Queue). Specifically, a request may remain on a CPU's deferred list until run_deferred() processes it; however, the R...

In the Linux kernel, the following vulnerability has been resolved: net/sched: fix packet loop on netem when duplicate is on When netem duplicates a packet it re-enqueues the copy at the root qdisc. If another netem sits in the tree the copy can be duplicated again, recursing until the stack or...
CVE-2026-63983
The CVE-2026-63983 entry concerns the Linux kernel net/sched component with netem, where duplicating a packet could cause recursive duplication loops in the qdisc tree, potentially exhausting stack or memory. Root cause: the old duplication guard invalidly zeroed q->duplicate around re-enqueue...
