commit 7500bb9cf164edbb2c8117d57620227b1a4a8369 upstream.
When allocation failures are not cleaned up by the driver, further allocation errors will be false-positives, which will cause buffers to remain uninitialized and cause NULL pointer dereferences. Ensure proper cleanup of failed allocations to prevent these issues.
