CVE-2026-46297

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified) openSUSE Tumbleweed versions prior to kernel-devel-7.0.12-1.1

Description An issue exists in the libwx network component where request threaded irq() is used with a primary handler but a NULL threaded handler, while simultaneously setting the IRQF ONESHOT flag. This combination triggers a kernel warning during the setup irq() function execution. The IRQF ONESHOT flag is intended to keep an interrupt line masked until the threaded handler has run to completion; using it without a threaded handler is an invalid configuration.

Recommendations For the Linux kernel, switch to the request irq() interface for non-threaded interrupt handlers and remove the IRQF ONESHOT flag. For openSUSE Tumbleweed, update to version kernel-devel-7.0.12-1.1.
