CWE ID Description
CWE-416 The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a Use After Free issue in Arm Ltd's Bifrost, Valhall, and 5th Gen GPU Architecture Userspace Drivers. It allows a non-privileged user process to perform valid GPU operations, such as through WebGL or WebGPU, to access memory that has already been freed. This means that the process can potentially read or manipulate memory that should no longer be accessible.


How can this vulnerability impact me? :

The vulnerability can allow a non-privileged user process to access freed memory, which may lead to unauthorized access to sensitive data, potential data corruption, or other unpredictable behavior in the system. This could compromise system stability or security by exposing memory contents that should be protected.
