CVE-2026-67855: n/a
A heap use-after-free vulnerability exists in open62541's GDS PushManagement certificate update workflow when UA_ENABLE_GDS_PUSHMANAGEMENT is enabled. This flaw allows a remote attacker to cause a denial of service by triggering memory corruption.
AI Analysis
Technical Summary
The open62541 library contains a heap use-after-free vulnerability in the GDS PushManagement certificate update workflow, which is active when the UA_ENABLE_GDS_PUSHMANAGEMENT feature is enabled. This vulnerability can be exploited remotely without authentication to cause a denial of service condition by corrupting memory. The CVSS v3.1 base score is 7.5, reflecting high severity due to the network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability (denial of service). No patch or official remediation has been disclosed at this time.
Potential Impact
A remote attacker can exploit this vulnerability to cause a denial of service by triggering a heap use-after-free condition in the affected component. There is no indication of confidentiality or integrity impact. No known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider disabling the UA_ENABLE_GDS_PUSHMANAGEMENT feature if feasible to reduce exposure.
