endpoint validation

Endpoint validation is a critical security practice in operating systems and drivers, as highlighted by CVE-2026-23312 affecting the Linux kernel's kaweth USB network driver. This vulnerability arose because the driver failed to verify that a USB device exposed the expected endpoints before binding, potentially leading to kernel crashes if a malicious or malformed device presented an unexpected layout. The fix involves checking the device's endpoints first to avoid dereferencing incorrect ones. This tag covers discussions about endpoint validation in the context of kernel security, driver reliability, and preventing crashes through proper hardware assumption checks.
