CVE-2026-98619 net: ethtool: keep rtnl_lock for the ioctl self test

In the Linux kernel, the following vulnerability has been resolved: net: ethtool: keep rtnllock for the ioctl self test An offline self test that brings the interface down and back up with netifclose / netifopen requires rtnllock for both. Since the ethtool IOCTL path became rtnl-optional for...

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: Handle maximum standalone channels Standalone channels use one NAPI vector for each Tx and Rx queue. fbnic's allocation path excludes FBNICMAXTXQS from that layout. A 64-Tx/64-Rx configuration therefore records 128...

CVE-2026-98618

The Linux kernel contains a vulnerability in the fbnic driver related to standalone channels. The issue arises because the driver's allocation path excludes FBNIC_MAX_TXQS from the layout. In a 64-Tx/64-Rx configuration, the system records 128 vectors but only allocates 64, resulting in NULL entr...

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: use the Rx queue napi pointer to find the napi vector The queue management ndos pick the napi vector for an Rx queue with: nv = fbn-napiidx % fbn-numnapi; The issue is this is only correct in the cases where there are...

CVE-2026-98617

The Linux kernel contains a vulnerability in the fbnic driver related to how NAPI vectors are selected for Rx queues. The issue stems from an incorrect calculation where the driver would occasionally point to Tx NAPI vectors instead of Rx ones when standalone Tx vectors were absent. The fix invol...

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: reset numnapi when the napi vectors are freed fbn-numnapi is the count of live napi vectors, each of which owns an IRQ. The PM path had freed them without clearing the count. fbnicpmsuspend tears the datapath down via...

CVE-2026-98616

The Linux kernel contains a vulnerability in the fbnic driver where the num_napi counter is not cleared when napi vectors are freed during power management (PM) operations. Specifically, fbnic_pm_suspend() frees IRQs without resetting the count, and certain failure scenarios—such as failed PCIe e...
