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.
