CVE-2026-15422 SCTP needs to better-check INIT ACK chunk parameters

The illumos SCTP inbound path performs association lookup for INIT ACK chunks without adequately validating the address parameters carried in the chunk. Since this lookup runs during packet classification i.e. before SCTP integrity checks or IPsec policy are applied a remote, unauthenticated...

CVE-2026-55548

In Yamcs, CVE-2026-55548 affects the PacketsApi.exportPackets endpoint. The root cause was failure to enforce per-packet ReadPacket privileges when a request supplied an empty packet-name list, causing no WHERE pname IN filter and the onTuple handler to stream packets without per-row authorizatio...

Name of the Vulnerable Software and Affected Versions Quicly versions prior to commit dccf5d4 Description Quicly, an IETF QUIC protocol implementation used in the H2O HTTP server, is susceptible to stateless reset injection. The issue stems from a lack of packet entry validation when handling...

JLSEC-2026-765 Remote packet capture support is disabled by default in libpcap

Remote packet capture support is disabled by default in libpcap. When a user builds libpcap with remote packet capture support enabled, one of the functions that become available is pcapfindalldevsex. One of the function arguments can be a filesystem path, which normally means a directory with...

CVE-2026-51807

Heap-based out-of-bounds write in j2kprecinctsubband::parsepacketheader in OpenHTJ2K versions 0.18.3 and earlier fixed in v0.18.4 caused by missing bounds validation before coding-pass lengths are written to j2kcodeblock::passlength128. A crafted JPEG 2000 codestream containing malformed PPM pack...

Integer underflow in wolfSSL packet sniffer = 5.9.0 allows an attacker to cause a program crash in the AEAD decryption path by injecting a TLS record shorter than the explicit IV plus authentication tag into traffic inspected by sslDecodePacket. The underflow wraps a 16-bit length to a large valu...
