CVE-2026-23105

CVE-2026-23105 (Linux kernel) : A fix in the net/sched/qfq code changes the activation check of a class from relying on the child qdisc’s qlen to using cl_is_active in qfq_rm_from_ag. This patch makes activation determination more consistent and aims to prevent exploits that could manipulate chil...

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...

kernel: i40e: add validation for ring_len param

A flaw was identified in the Intel “i40e” Ethernet driver in the Linux Kernel where the ringlen parameter supplied by a VF virtual function is passed unchecked to the hardware memory context. If a malicious Virtual function provides a too-large or misaligned ringlen, it may allow the device to...
