Description

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