How the Exploit Works
The exploit takes advantage of an out of bounds write due to a heap buffer overflow within the ConvertReductionOp function in darwinn_mlir_converter_aidl.cc. This buffer overflow could potentially allow an attacker to write arbitrary data to privileged memory areas, potentially leading to a local escalation of privilege. As no user interaction is required, this vulnerability could be exploited without the user’s knowledge.
Conceptual Example Code
Here’s a conceptual representation of how this vulnerability might be exploited. This pseudocode example demonstrates an attempt to overflow the heap buffer:
#include <stdlib.h>
int main() {
int* buffer = (int*) malloc(10 * sizeof(int));
for (int i = 0; i <= 10; i++) {
buffer[i] = i; // The 11th iteration causes a buffer overflow
}
return 0;
}Please note that this is a simplified example. The actual exploitation would depend on the specific implementation details of the affected software.
