Description Vladimir Vasilev 2026-09-15 18:28:21 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.

FreeRDP before 3.31.0 contains a use-after-free vulnerability in the smartcard RDPDR device handler when worker thread creation fails after device registration. Attackers can trigger thread creation failure during channel setup to cause device pointer deallocation while devman retains a reference, leading to crash or code execution.
