Description Marian Rehak 2026-08-05 13:01:30 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

open62541 contains a heap use-after-free in the GDS PushManagement certificate update workflow when UA_ENABLE_GDS_PUSHMANAGEMENT is enabled. This allows a remote attacker to cause a denial of service.
Comment 1 Aoife Moloney 2026-08-17 15:47:01 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
