0 A security vulnerability exists in libsoup's WebSocket frame processing when the maximum incoming payload size is unset or set to zero. This can lead to out-of-bounds memory reads, potentially causing memory exposure or application crashes. The issue requires a non-default configuration and is not enabled by default in typical deployments. The vulnerability is rated medium severity and affects certain versions of libsoup used in SUSE products.

The fix for CVE-2026-0716 (commit 6ff7ef0, libsoup 3.6.6) placed the integer overflow guard inside the if (masked) block, leaving unmasked server-to-client frames unprotected. A malicious WebSocket server can send a crafted unmasked frame with a payload length near UINT64_MAX to trigger an OOB read in a libsoup-based client when max_incoming_payload_size is set to 0.
