CVE-2026-46041

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified) openSUSE Tumbleweed versions prior to kernel-devel-7.0.11-1.1

Description A flaw exists in the greybus gb-beagleplay component where the hdlc append() function calls usleep range() while the tx producer lock spinlock is held via hdlc tx frames(). Sleeping while holding a spinlock is an illegal operation that can trigger a "BUG: scheduling while atomic" error. The issue occurs because the wait for circular buffer space happens within an atomic context.

Recommendations For openSUSE Tumbleweed, update to version kernel-devel-7.0.11-1.1. At the moment, there is no information about a newer version that contains a fix for this vulnerability for the Linux kernel.
