This feature uses the getpeername() function, passing a buffer of\nsufficient length to hold any supported address family, but passes a buffer\nlength that is only sized such that larger addresses, such as IPv6, cannot be\nretrieved. The getpeername() function however, still returns the full address\nlength, which is accepted as the valid input buffer length, leading to the\naddress buffer containing uninitialized stack data instead of the actual peer\naddress. The invalid peer address is then used as destination for the outgoing\npackets which leads to a connectivity breakage and a leakage of the\nuninitialized stack data to passive network observers.\n\nFIPS impact: no\nThe FIPS modules in 4.0, 3.6, 3.5, 3.4, and 3.0 are not affected by this CVE as\nthe affected protocol is not implemented in the FIPS module."}]},{"artifact":{"id":"1aa0edd3366adca1","cpes":["cpe:2.3:a:libssl3t64:libssl3t64:3.5.7-1\\~deb13u3:*:*:*:*:*:*:*"],"name":"libssl3t64","purl":"pkg:deb/debian/libssl3t64@3.5.7-1~deb13u3?arch=amd64&distro=debian-13.7&upstream=openssl","type":"deb","version":"3.5.7-1~deb13u3","language":"","licenses":["Apache-2.0","Artistic","GPL-1","GPL-1+"],"locations":[{"path":"/var/lib/dpkg/status.d/libssl3t64","layerID":"sha256:2cef49adb7d7902c61ecdd385036e3c7fb7c9f0ada96a41901797c77b7daedd7","accessPath":"/var/lib/dpkg/status.d/libssl3t64","annotations":{"evidence":"primary"}},{"path":"/usr/share/doc/libssl3t64/copyright","layerID":"sha256:2cef49adb7d7902c61ecdd385036e3c7fb7c9f0ada96a41901797c77b7daedd7","accessPath":"/usr/share/doc/libssl3t64/copyright","annotations":{"evidence":"supporting"}},{"path":"/var/lib/dpkg/status.d/libssl3t64.md5sums","layerID":"sha256:2cef49adb7d7902c61ecdd385036e3c7fb7c9f0ada96a41901797c77b7daedd7","accessPath":"/var/lib/dpkg/status.d/libssl3t64.md5sums","annotations":{"evidence":"supporting"}}],"upstreams":[{"name":"openssl"}]},"matchDetails":[{"type":"exact-indirect-match","found":{"vulnerabilityID":"CVE-2026-95691","versionConstraint":"none (unknown)"},"matcher":"dpkg-matcher","searchedBy":{"distro":{"type":"debian","version":"13.7"},"package":{"name":"openssl","version":"3.5.7-1~deb13u3"},"namespace":"debian:distro:debian:13"}}],"vulnerability":{"id":"CVE-2026-95691","fix":{"state":"not-fixed","versions":[]},"cvss":[],"cwes":[{"cve":"CVE-2026-95691","cwe":"CWE-416","type":"Secondary","source":"openssl-security@openssl.org"}],"epss":[{"cve":"CVE-2026-95691","date":"2026-11-12","epss":0.0019,"percentile":0.08743}],"risk":0.095,"urls":[],"severity":"Unknown","namespace":"debian:distro:debian:13","advisories":[],"dataSource":"https://security-tracker.debian.org/tracker/CVE-2026-95691","description":"Issue summary: A retransmitted QUIC CRYPTO frame can release packet storage while the TLS record layer retains a direct pointer into that storage causing use after free.

Impact summary: An attacker able to supply the recipient certificate to an application performing CMS encryption can cause that application to loop indefinitely, consuming CPU and resulting in Denial of Service.  CWE: CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop')  Description: CMS_encrypt() and CMS_encrypt_ex() encrypt a message to one or more recipient certificates and, for an EC recipient, generate an ephemeral key in the recipient's group. If the certificate declares a group order of 1, random scalar generation can only produce zero. The key generation routine then retries without limit while waiting for a nonzero private scalar, so the call never returns.  The OpenSSL TLS and QUIC implementations do not use this path. An application is exposed only if it calls CMS_encrypt() or CMS_encrypt_ex() with a recipient certificate whose EC parameters are attacker-controlled. Certificates with normal EC group orders do not trigger the loop.  OpenSSL 4.0 and later reject unknown explicit EC groups in default builds. These versions are affected only when configured with the enable-ec_explicit_curves option.  The result is a hang that consumes a CPU core until the process is interrupted, a Denial of Service. The severity is Low because the attacker must supply the recipient certificate and the application must choose to encrypt to it; ordinary CMS encryption to trusted recipients is unaffected.
