CVE-2026-90071

CVE-2026-90071 is a use-after-free (UAF) in the Linux kernel's TEQL (Traffic Engineering Load Balancing) QoS scheduler (net/sched/sch_teql). The function teql_master_xmit() sets skb->dev to the current slave before attempting transmit but fails to restore it when the transmit fails. The skb th...

In the Linux kernel, the following vulnerability has been resolved: net/sched: schteql: restore skb-dev on the slave failure path teqlmasterxmit sets skb-dev = slave before calling the slave's ndostartxmit, but never restores it when that transmit fails. The skb then walks on to the next slave...

CVE-2026-90071: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net/sched: schteql: restore skb-dev on the slave failure path teqlmasterxmit sets skb-dev = slave before calling the slave's ndostartxmit, but never restores it when that transmit fails. The skb then walks on to the next slave...

The vulnerability of the teql_master_xmit() function in the net/sched/sch_teql.c module of the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the teqlmasterxmit function in the net/sched/schteql.c module of the Linux operating system is related to pointer manipulation. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2026-72390: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net/sched: schteql: Introduce slaveslock to avoid race condition and UAF The teql master-slaves singly linked list is not protected against multiple writes. It can be mod'ed concurently from teqlmasterxmit, teqldequeue, teqlinit...

CVE-2026-23449: Double Free

In the Linux kernel, the following vulnerability has been resolved: net/sched: teql: Fix double-free in teqlmasterxmit Whenever a TEQL devices has a lockless Qdisc as root, qdiscreset should be called using the seqlock to avoid racing with the datapath. Failure to do so may cause crashes like the...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the fact that teqlmasterxmit does not update the skb-dev pointing to the slave device before sending...
