Description Srikanth Balasubramanian 2026-08-04 11:28:31 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 3.29.0 contains a null pointer dereference vulnerability in smartcard device control request cleanup when reader-state decoding fails. Attackers can send malformed smartcard IRP requests with non-zero cReaders and truncated reader-state data to crash the process via null pointer access in free_reader_states functions.
Comment 1 Ondrej Holy 2026-08-07 08:54:14 UTC 
freerdp-2.11.7 does not contain free_reader_states_a() or the affected NDR parsing pattern (introduced in FreeRDP 3.x)
