Technical Analysis

Red Hat issued a security advisory (RHSA-2026:47009) for Red Hat Hardened Images RPMs that includes fixes for multiple CVEs, notably CVE-2026-59251, a denial of service vulnerability in Erlang/OTP's public_key application. The vulnerability arises from improper resource allocation limits during TLS certificate path validation, which can be exploited remotely without authentication by sending crafted X.509 certificate chains. This leads to excessive CPU and memory usage, causing the Erlang Virtual Machine to crash. The advisory lists updated erlang27 RPM packages (version 27.3.4.15-0.1.hum1) for aarch64 and x86_64 architectures that address these issues. Red Hat provides detailed references and encourages applying the update to mitigate the risk.

Potential Impact

The vulnerability allows remote unauthenticated attackers to cause a denial of service by crashing the Erlang VM through resource exhaustion during TLS certificate validation. This impacts availability but does not affect confidentiality or integrity. The advisory rates the severity as critical due to the potential for service disruption. No active exploitation in the wild has been reported.

Mitigation Recommendations

Red Hat has released updated RPM packages (erlang27 version 27.3.4.15-0.1.hum1) that fix the vulnerabilities described. Users should apply these official updates to affected Red Hat Hardened Images to remediate the issue. No alternative mitigations or workarounds are specified in the advisory. Patch status is confirmed as fixed in the provided updated packages.
