CVE-2026-99282

The Linux kernel contains a use-after-free vulnerability in the net/sched component, specifically within the sch_teql qdisc. The root cause is that teql_master_xmit() incorrectly tests the slave's ndo_start_xmit() return value against NETDEV_TX_OK alone. When a slave (such as a VLAN slave ) consu...

EUVD-2026-119280

In the Linux kernel, the following vulnerability has been resolved: net/sched: schteql: fix use-after-free on lower qdisc drop The issue: teqlmasterxmit tests the slave's ndostartxmit return value against NETDEVTXOK alone. A slave that consumes the skb but returns an error code rc dev and calls...

Astra Linux – vulnerability in linux-6.1

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; however, it never restores skb-dev when the transmission fails. As a result, the skb...

CVE-2026-90071

A flaw was found in the Linux kernel's network scheduler component schteql. An issue exists where the skb-dev pointer is not correctly restored after a slave device transmit failure. This can result in a Use-After-Free UAF vulnerability if the associated network device is subsequently freed while...

ROS-20260930-73-0078

The vulnerability of the schteql component in the Linux operating system’s kernel is related to the dereferencing of a pointer whose validity has expired. Exploiting this vulnerability can allow an attacker to trigger a service failure...
