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

In the Linux kernel, the following vulnerability has been resolved: net: mctp: i3c: serialize probe with bus removal mctpi3cprobe drops busdevslock after finding the matching bus. A concurrent I3CNOTIFYBUSREMOVE can then unregister and free the bus netdev before probe passes its private data to...

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...

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix use-after-free race in samplerestoreput Concurrent teardown of TC sample rules sharing the same restore context may re-read restore-count after dropping restorelock. At that point another thread may already have...

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

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: E-Switch: fix use-after-free in mlx5eswitchtermtblput In mlx5eswitchtermtblput, the zero-ref cleanup check reads tt-refcount after termtblmutex has been released. Two concurrent callers on the same mlx5termtblhandle rac...

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-2026-98014 net/mlx5: E-Switch, prevent mc_list repopulation during vport disable

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: E-Switch, prevent mclist repopulation during vport disable In mlx5eswvportdisable, move eswapplyvportrxmode ahead of eswvportchangehandlelocked so vport-allmultirule is NULL before the change handler observes it. During...

During...

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...
