CVE-2026-48497

Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.35.11, 1.36.7, 1.37.3, and 1.38.1, in cases where UDP DNS filter is configured with local resolution containing a name with the length of 255 octets or remote resolution for a name of 255 octets long...

CVE-2026-48497

Envoy CVE-2026-48497 affects the UDP DNS filter when local or remote resolution yields a name of 255 octets. In versions prior to 1.35.11, 1.36.7, 1.37.3, and 1.38.1, such a DNS query can trigger abnormal process termination due to an invalid runtime precondition that the name must be strictly le...

CVE-2026-47778

Envoy CVE-2026-47778 describes a TLS DNS SAN truncation flaw in DefaultCertValidator::verifySubjectAltName. Before 1.35.11, 1.36.7, 1.37.3, and 1.38.1, an embedded NUL in a dNSName SAN can be partially preserved by generalNameAsString but truncated when converted to a C-style string via .c_str(),...

CVE-2026-46611

Glances XML-RPC server (glances/server.py) before 4.5.5 does not validate the HTTP Host header, enabling DNS rebinding attacks to exfiltrate the victim’s monitoring data. The vulnerability affects the XML-RPC backend used by glances -s (XML-RPC path /RPC2) and allows an attacker to cause the brow...

CVE-2026-56123

socat versions 1.8.0.0 through 1.8.1.1 contain a heap-based buffer overflow vulnerability that allows a malicious SOCKS5 proxy server to overwrite adjacent heap memory by exploiting a sign-extension flaw in the DOMAINNAME reply parser. During connection setup, the domain name length byte is read...

CVE-2026-56123 socat 1.8.0.0 - 1.8.1.1 Heap Buffer Overflow via SOCKS5 Reply Parser

socat versions 1.8.0.0 through 1.8.1.1 contain a heap-based buffer overflow vulnerability that allows a malicious SOCKS5 proxy server to overwrite adjacent heap memory by exploiting a sign-extension flaw in the DOMAINNAME reply parser. During connection setup, the domain name length byte is read...

CVE-2026-56123

CVE-2026-56123 affects socat versions 1.8.0.0 through 1.8.1.1. A signed-char sign-extension bug in the DOMAINNAME reply parser during SOCKS5 handshake allows a negative bytes_to_read value to be implicitly converted to size_t, causing an unbounded heap write into a 262-byte reply buffer. This res...
