CVE-2026-15714

The CVE concerns libsoup, specifically the soup_multipart_input_stream_read_headers() function in soup-multipart-input-stream.c, where the boundary size is not adequately validated. A crafted HTTP response with a malformed or oversized multipart boundary allows an out-of-bounds read, enabling a r...

CVE-2026-15714 Libsoup: soupmultipartinputstream: libsoup: out-of-bounds read in soup_multipart_input_stream_read_headers via an oversized multipart boundary string

An out-of-bounds read vulnerability was found in libsoup's multipart processing subsystem. The flaw exists in the soupmultipartinputstreamreadheaders function inside soup-multipart-input-stream.c, which does not adequately restrict or validate the size of incoming multipart boundary strings. When...

CVE-2026-15713

This CVE affects Libsoup’s HTTP/2 implementation. The issue is a memory leak where memory context blocks are not properly released under specific stream termination conditions (e.g., window exhaustion or explicit stream resets). A remote, unauthenticated attacker acting as a malicious network pee...

CVE-2026-15713 Libsoup: soupcache: libsoup: http/2 frame window exhaustion remote denial of service via memory leak

A vulnerability was found in libsoup's HTTP/2 protocol implementation. The library fails to correctly release memory context blocks under specific stream termination conditions, such as when an HTTP/2 connection encounters window exhaustion or explicit stream resets. A remote, unauthenticated...

CVE-2026-15711 Libsoup: soupwebsocketconnection: libsoup: websocket remote denial of service via oversized control frame protocol violation

A vulnerability was found in libsoup's WebSocket frame parsing implementation. The library fails to validate length rules specified in RFC 6455 §5.5, which mandates that all WebSocket control frames e.g., PING, PONG, CLOSE contain a payload of 125 bytes or less. A remote, unauthenticated attacker...

CVE-2026-15711

The CVE describes a vulnerability in libsoup’s WebSocket frame parsing. The flaw stems from failing to validate length rules for WebSocket control frames as specified in RFC 6455 §5.5, allowing an oversized control frame to be sent by a remote, unauthenticated attacker. The parser does not termin...

CVE-2026-15709 Soupwebsocketextensiondeflate: libsoup: libsoup: websocket permessage-deflate unbounded decompression remote denial of service

A flaw was found in libsoup's WebSocket implementation when using the permessage-deflate extension. The extension's decompression loop inflate processes data in chunks without enforcing an upper boundary limit on the output buffer size. While libsoup limits the incoming compressed frame size via...

CVE-2026-15709

The CVE concerns libsoup's WebSocket permessage-deflate implementation. The decompression loop (inflate()) can allocate memory without an upper bound, as output size is not bounded during decompression even though max_incoming_payload_size limits input frames. A separate check for decompressed si...

CVE-2026-15712

A heap buffer over-read vulnerability was discovered in libsoup's versions: libsoup 3.0 to 3.7.0 HTTP/2 connection tracking framework. When the library processes an HTTP/2 GOAWAY frame, it improperly handles the "Additional Debug Data" payload by assuming the data stream is a safely NUL-terminate...

CVE-2026-15712

CVE-2026-15712 affects libsoup’s HTTP/2 connection tracking in/libsoup3 (versions 3.0–3.7.0) where the GOAWAY frame’s Additional Debug Data is parsed as a NUL-terminated C-string without strict length checks. This permits a remote, unauthenticated attacker to send malformed GOAWAY frames, causing...
