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.","cvssScore":8.6,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H","cwes":["CWE-125"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-102557","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2543231","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
