CVE-2026-46297 Details
Description
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.
A vulnerability has been identified in the Linux kernel's handling of virtual function (VF) miscellaneous interrupts within the net: libwx component. The issue arises from the use of request_threaded_irq() with a primary handler and a NULL threaded handler, while also applying the IRQF_ONESHOT flag. This combination triggers a warning, as it violates the expected usage of threaded interrupt handlers. The vulnerability affects several versions of the Linux kernel.
The vulnerability has been addressed by modifying the interrupt handling to use request_irq() instead of request_threaded_irq(), removing the IRQF_ONESHOT flag. Users should apply the latest patches available in the Linux kernel stable tree to mitigate this issue.
