Affected versions of this package are vulnerable to Improper Handling of Length Parameter Inconsistency.
in the fallback_buf process. An attacker can access sensitive memory contents by triggering a CPU mismatch that causes the system to read beyond the bounds of the fallback buffer and leak adjacent memory into telemetry. This is only exploitable if context propagation is enabled, the tpinjector sock_msg path is active, HTTP large-buffer capture is configured with a non-zero size, and a CPU mismatch occurs between producer and consumer contexts.
