    Arm 5th Gen GPU Architecture Kernel Driver | r41p0 through r49p3, r50p0 through r53p0

    How the Exploit Works

    In the context of a Use After Free vulnerability, an attacker exploits the improper processing of GPU memory operations by accessing memory that has already been freed. This allows the attacker to read from, write to, or execute code from memory locations that should not be accessible. As a result, the attacker can gain control over the system or leak sensitive data.

    Conceptual Example Code

    While the exact code to exploit this vulnerability is beyond the scope of this article, a conceptual example might look something like this:

    void exploit() {
    char* ptr = malloc(100);   // Allocate 100 bytes
    free(ptr);                 // Free the allocated memory
    strcpy(ptr, "malicious_payload");  // Write to the freed memory
    execute(ptr);              // Execute the malicious payload
    }

    In this conceptual example, memory is allocated and then freed. Following that, the same memory space is used to store a malicious payload, which is then executed. This demonstrates the essence of a Use After Free vulnerability, where the freed memory is not properly managed and can be accessed post-deallocation.
