kernel: Linux kernel: Use-after-free in teql queueing discipline can lead to privilege escalation

A flaw was found in the Linux kernel's networking component. A local attacker with low privileges could exploit a design issue in the teql queueing discipline, which is responsible for managing network traffic. By sending specially crafted network packets, an attacker could trigger a use-after-fr...

CVE-2026-23074

CVE-2026-23074 is a Linux kernel vulnerability in net/sched teql where the teql queuing discipline may be used outside its intended root qdisc, allowing a crafted packet sequence to create a use-after-free scenario in the qfq/qos path due to queue length (qlen) handling. The root cause is that te...
