CVE-2026-23347

About vulnerability

In the Linux kernel, the following vulnerability has been resolved: can: usb: f81604: correctly anchor the urb in the read bulk callback When submitting an urb, that is using the anchor pattern, it needs to be anchored before submitting it otherwise it could be leaked if usb_kill_anchored_urbs() is called. This logic is correctly done elsewhere in the driver, except in the read bulk callback so do that here also. A flaw was found in the Linux kernel’s can: usb: f81604 driver. When a USB Request Block (urb) is submitted, it is not correctly anchored in the read bulk callback. This oversight could lead to a resource leak if usb_kill_anchored_urbs() is called, potentially resulting in a Denial of Service (DoS) due to resource exhaustion.

Live-patch status from KernelCare for each operating system.
