Detailsinfo

A vulnerability was found in Linux Kernel up to 6.9.7. It has been declared as problematic. This vulnerability affects the function cxacru_bind of the file drivers/usb/core/urb.c of the component usb. The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: usb: atm: cxacru: fix endpoint checking in cxacru_bind() Syzbot is still reporting quite an old issue [1] that occurs due to incomplete checking of present usb endpoints. As such, wrong endpoints types may be used at urb sumbitting stage which in turn triggers a warning in usb_submit_urb(). Fix the issue by verifying that required endpoint types are present for both in and out endpoints, taking into account cmd endpoint type. Unfortunately, this patch has not been tested on real hardware.
