CVE-2026-46297 is a vulnerability in Linux Kernel
Published on June 8, 2026
net: libwx: use request_irq for VF misc interrupt
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.
