In the Linux kernel, the following vulnerability has been resolved: mailbox: bcm2835: Fix timeout during suspend mode During noirq suspend phase the Raspberry

In the Linux kernel, the following vulnerability has been resolved: mailbox: bcm2835: Fix timeout during suspend mode During noirq suspend phase the Raspberry Pi power driver suffer of firmware property timeouts. The reason is that the IRQ of the underlying BCM2835 mailbox is disabled and rpi_firmware_property_list() will always run into a timeout [1]. Since the VideoCore side isn't consider as a wakeup source, set the IRQF_NO_SUSPEND flag for the mailbox IRQ in order to keep it enabled during suspend-resume cycle.

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 0.26%, higher than 17% 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.
