Stack-Out-of-Bounds Read Vulnerability in Linux Kernel's HID Thrustmaster Driver

CVE-2025-21794

What is CVE-2025-21794?

A stack-out-of-bounds read vulnerability in the HID Thrustmaster driver can lead to kernel crashes due to improper handling of the ep_addr array within the usb_check_int_endpoints function. This occurs when the function attempts to read beyond the bounds of the array, resulting in a crash. To mitigate this issue, a zero element has been added at the end of the array to ensure that the for loop terminates correctly, preventing excessive reads and maintaining kernel stability.
