CVE-2026-98427

A flaw was found in the Linux kernel's CoDel Controlled Delay network packet scheduling subsystem. An unprivileged local user can trigger a Denial of Service DoS by configuring extremely small packet intervals on network queues. This flaw causes the packet-dropping logic to enter an unbounded loo...

CVE-2026-98012

A flaw was found in the Linux kernel's Stochastic Fairness Queueing SFQ network packet scheduling subsystem. A local attacker with network administration privileges, including within an unprivileged user namespace, can supply an improperly bounded quantum parameter alongside a crafted packet size...

CVE-2026-72036

A flaw was found in the Linux kernel's schmultiq component, which handles network packet scheduling. This vulnerability occurs when a non-work-conserving child queue is improperly handled after a packet has been temporarily stored. This can lead to a desynchronization of network packet queues and...

Linux kernel sch_atm Heap Buffer Overflow DoS

The vulnerability of the atmtcenqueue function in the network packet scheduling subsystem net/sched/schatm.c of the Linux kernel is related to an incorrect definition of the class type. Exploiting this vulnerability could allow an attacker to cause service failures...
