Technical Summary
CVE-2026-46917 is a vulnerability in the OpenJDK DTLS implementation that permits two different denial of service attacks by causing uncontrolled resource consumption. This can result in crashes, exits, restarts, or resource exhaustion such as CPU or memory, preventing legitimate users from accessing the affected product. The vulnerability is tracked under CWE-400 (Uncontrolled Resource Consumption) and related CWEs indicating protection mechanism bypass and memory issues. Red Hat has issued an advisory and released updated RPM packages for Red Hat Hardened Images to fix this issue.
Potential Impact
The vulnerability allows an attacker to cause denial of service by exhausting resources during DTLS handshaking, leading to potential crashes or degraded service availability. There is no impact on confidentiality or integrity. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Red Hat has released updated RPM packages for Red Hat Hardened Images that fix this vulnerability. Users should apply the updates as provided in the Red Hat advisory (RHSA-2026:46808) to remediate the issue. No additional mitigations are specified or required once the update is applied.
