CVE-2024-41097 is an improper input-validation flaw in the Linux kernel USB ATM CXACRU driver. During device binding, cxacru_bind() incompletely validated the presence and types of USB endpoints. A device presenting unsuitable endpoint descriptors could cause the driver to select an endpoint of the wrong transfer type and subsequently submit a USB Request Block (URB) with an inconsistent pipe/type combination. The kernel detects this condition in usb_submit_urb() and emits a BOGUS URB transfer warning. The fix validates the required input and output endpoint types, including the command endpoint type, before continuing device initialization.

Linux kernel cxacru USB ATM driver flaw involving endpoint validation in cxacru_bind().
A Linux kernel cxacru USB ATM driver flaw caused by incomplete validation of required USB endpoint types in cxacru_bind(). Incorrect endpoint types could subsequently be used when submitting URBs, producing a usb_submit_urb() warning. The fix validates required inbound and outbound endpoint types, including the command endpoint type.
