CVE-2026-98026

The Linux kernel contains a vulnerability in the net: bridge: mcast component where the br_multicast_del_port_group function unlists a port group without using the proper RCU helper to preserve the next pointer. Consequently, the port group is freed immediately without waiting for the RCU grace p...

CVE-2026-98022

The Linux kernel contains a vulnerability where several subsystems (pfifo_fast , tun , and tap ) allocate ring buffers based on dev->tx_queue_len without an upper bound. An unprivileged user using unshare -Urn can set an excessively large tx_queue_len to exhaust global memory via oversized rin...

CVE-2026-98017

The Linux kernel contains a vulnerability in the net/sched component where an RTM_NEWQDISC request can cause a clsact to bind a populated shared ingress block during ->init() . If the request contains an invalid TCA_RATE , the estimator setup fails, causing the unwind process to synchronously ...

CVE-2026-98018

A vulnerability exists in the Linux kernel within the net: mctp: i3c component. The root cause is that mctp_i3c_probe() drops the busdevs_lock prematurely after finding the matching bus. This allows a concurrent I3C_NOTIFY_BUS_REMOVE event to unregister and free the bus netdev before the probe ca...

CVE-2026-98016

The Linux kernel contains a use-after-free race condition within the net/mlx5e component, specifically in the sample_restore_put() function. The vulnerability occurs during the concurrent teardown of TC sample rules sharing the same restore context; a thread may re-read restore->count after dr...

CVE-2026-98015

The Linux kernel contains a use-after-free vulnerability in the net/mlx5: E-Switch component within the mlx5_eswitch_termtbl_put() function. The issue arises because the tt->ref_count cleanup check occurs after the termtbl_mutex has been released, allowing a race condition where one caller fre...

CVE-2026-98014

The Linux kernel contains a vulnerability in the net/mlx5 driver related to E-Switch functionality. During FW-fatal recovery (where dev->state == INTERNAL_ERROR), a failure in esw_update_vport_rx_mode() leaves vport->allmulti_rule intact. This causes esw_update_vport_mc_promisc() to add ent...

CVE-2026-98013

The Linux kernel contains a vulnerability in the net/sched component within the fq_pie qdisc. The fq_pie_change() function improperly accepts any quantum value from userspace, including a value of 1. When combined with a crafted size table where qdisc_pkt_len reaches approximately 2 GiB , a quant...
