CVE-2026-74317: In the Linux kernel, the following vulnerability has been resolved: ixgbe: do not configure xps for XDP queues netif_set_xps

In the Linux kernel, the following vulnerability has been resolved: ixgbe: do not configure xps for XDP queues netif_set_xps_queue() should not be called for

In the Linux kernel, the following vulnerability has been resolved: ixgbe: do not configure xps for XDP queues netif_set_xps_queue() should not be called for an XDP Tx queue, since such queues are not netdev-exposed. On systems with number of CPUs >=64, on E610 adapter, netdev is configured with maximum number queue pairs being 63 (due to MSI-X assignment), but configuring XDP results in 64 XDP queues. So, during XDP program load, when netif_set_xps_queue() is called for the last XDP queue, we get a WARNING with a call trace and KASAN report afterwards (if enabled).

What it means for a small business

Linux is on the computers, phones or browsers your team uses every day. Turn on automatic updates and restart: most of these fixes only take effect after a restart.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.13%, higher than 2% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 29, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
