Input Validation Flaw in Linux Kernel's AMDGPU Component

CVE-2025-40335

What is CVE-2025-40335?

This vulnerability pertains to the AMDGPU component of the Linux kernel, where there is an issue with the validation of user input parameters in userq requests. An improper validation process can lead to the acceptance of invalid commands, potentially compromising system integrity during IOCTL (Input/output control) operations. The resolution improves the validation mechanism for userq input arguments, ensuring that only valid requests are processed, thus enhancing overall security.
