CVE-2026-46297

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. 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.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: net: libwx: usar request_irq para interrupción miscelánea de VF Actualmente, se usa request_threaded_irq() con un gestor primario pero un gestor en hilo NULL, mientras también se establece la bandera IRQF_ONESHOT. Esta combinación específica dispara una ADVERTENCIA desde el commit aef30c8d569c ('genirq: Advertir sobre el uso de IRQF_ONESHOT sin un gestor en hilo'). ADVERTENCIA: kernel/irq/manage.c:1502 en __setup_irq+0x4fa/0x760 Se corrige el problema cambiando a request_irq(), que es la interfaz apropiada o un gestor de interrupciones no en hilo, y eliminando la bandera IRQF_ONESHOT innecesaria.
