CVE-2025-21916

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw in existing endpoint checks in the Linux kernel's usb: atm: cxacru module has been identified by Syzbot. The issue arises from incomplete endpoint testing, which can be resolved by switching the endpoint verification approach to usb check XXX endpoints() instead of relying on usb find common endpoints(). This change ensures that the endpoint's address is also checked, in addition to the number and types of endpoints.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
