CVE-2026-102557 [HIGH] – A flaw was found in libsoup. When reassembling fragmented WebSocket messages into a GByteA

A flaw was found in libsoup. When reassembling fragmented WebSocket messages into a GByteArray, libsoup did not adequately cap total message size against the limits of the underlying buffer type. A remote peer could send fragments that caused size truncation while the implementation still used the full length, leading to heap corruption or a crash.
