CVE-2026-46297
In the Linux kernel, the following vulnerability has been resolved: net: libwx: use request_irq for VF misc interrupt Currently, request_threaded_irq() is used with a primary handler but a NULL threaded handler, while also setting the IRQF_ONESHOT flag. This specific combination triggers a WARNING since the commit aef30c8d569c ("genirq: Warn about using IRQF_ONESHOT without a threaded handler"). WARNING: kernel/irq/manage.c:1502 at __setup_irq+0x4fa/0x760 Fix the issue by switching to request_irq(), which is the appropriate interface or a non-threaded interrupt handler, and removing the unnecessary IRQF_ONESHOT flag.
