In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix the error "trying to register non-static key in rxe_cleanup_task" In the fun

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix the error "trying to register non-static key in rxe_cleanup_task" In the function rxe_create_qp(), rxe_qp_from_init() is called to initialize qp, internally things like rxe_init_task are not setup until rxe_qp_init_req(). If an error occurred before this point then the unwind will call rxe_cleanup() and eventually to rxe_qp_do_cleanup()/rxe_cleanup_task() which will oops when trying to access the uninitialized spinlock. If rxe_init_task is not executed, rxe_cleanup_task will not be called.

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 0.19%, higher than 9% 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.
