5.5 · MEDIUMOverview
CVE-2026-46297 is a medium-severity vulnerability affecting linux linux_kernel. It was published on June 8, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
