In the Linux kernel, the following vulnerabilities have been resolved: sch/netem: fixed the use of memory after deallocation in netemdequeue. If netemdequeue enqueues a packet to an inner qdisc, and that qdisc returns NETXMITSTOLEN. As a result, the packet is dropped, but qdisctreereducebacklog i...

In the Linux kernel, the following vulnerability has been resolved: net/sched: netem: account for backlog updates from child qdisc Generally, the ‘qlen’ of any classful qdisc should track the number of packets held by the qdisc itself and all its children. In the case of netem, ‘qlen’ only accoun...

CVE-2026-31675

A flaw was found in the Linux kernel's netem network emulator module. When processing certain non-linear network packets, specifically those sent via an AFPACKET TXRING over an IPIP tunnel, a calculation error can occur. This error leads to an out-of-bounds memory access, which could result in...
