FreeRDP from 3.11.0 before 3.32.2 contains an assertion failure in the RemoteFX RLGR decoder that allows malicious servers to terminate clients. Attackers controlling an RDP server can send a RemoteFX tileset with RLGR code 32767, triggering a signed narrowing assertion in rfx_rlgr_decode and crashing the client.

The Rocky Linux 10.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-2026_94514 advisory.
