CVE-2026-14457 Details
Issue summary: In a server or client configuration with RFC7250 Raw Public Keys (RPKs)
enabled, and only the private key (with no associated certificate) configured locally,
a NULL pointer dereference may occur when the remote peer solicits raw public keys and
also sends the typically omitted "signature_algorithms_cert" TLS extension.

Impact summary: The impact is limited to a possible Denial of Service as a result of
an application abort, no data disclosure or remote command execution are possible.

CWE: CWE-476: NULL Pointer Dereference

Description: While a passing comment in sample code in the documentation suggests
that key-only RPK configurations are supported, the best-practice RPK configuration
is to always configure a corresponding certificate (possibly self-signed or
signed by any convenient CA).

When the private key is configured along with a matching certificate, the
"signature_algorithms_cert" extension is handled reliably even without the
fix, and peer clients or servers that don't support raw public keys may be
able to complete a TLS connection by pinning or verifying the corresponding
certificate or its public key.

Deployments that prefer to configure just a private key with no certificate
need to upgrade to an updated release as noted below.

FIPS impact: no

No FIPS modules are affected by this issue, as the SSL protocol implementation
is outside the OpenSSL FIPS module boundary.

Exploit prediction scoring system (EPSS) score for CVE-2026-14457
EPSS (Exploit Prediction Scoring System): EPSS predicts the likelihood that a vulnerability will be exploited in the wild. A higher percentage means a greater chance of an exploit occurring. The EPSS model produces a probability score between 0 and 1 (0 and 100%).
1.17 Probability of exploitation activity being observed over the next 30 days (67th percentile)
CVSS score for CVE-2026-14457
CVSS (Common Vulnerability Scoring System): An open framework owned and managed by FIRST.Org, Inc. that assigns a numerical score from 0 to 10 to software vulnerabilities to indicate their severity.

Bitsight Data Discovery and Continuous Threat Scanning

Bitsight, the leading provider in Cyber Risk Management, introduced the next-generation internet scanner Bitsight Groma in May 2024. This technology continuously scans the entire internet to discover assets, collect asset attribution evidence, and identify an ever-growing set of security observations, such as vulnerabilities and misconfigurations. Groma’s scanning activities presently encompass:


  • 40 million-plus monitored organizations
  • 250 million-plus host names
  • 4 billion-plus routable IPv4 and IPv6 addresses

Greynoise’s recent study testifies the speed of Bitsight Groma.
