CVE-2026-110833: FreeRDP RDPDR Proxy Memory Consumption Vulnerability

Sources read

Source agreement

0/2

Evidence confidence

%37

Short explanation

FreeRDP contains a resource consumption vulnerability in the proxy component due to the failure to enforce cumulative or absolute size limits when reassembling RDPDR channel fragments.

Why does it matter?

This vulnerability can allow attackers to exhaust proxy memory, leading to a denial of service. Sources exhibit discrepancies regarding the CVSS base score and severity level.

What should be done?

Update FreeRDP to version 3.32.0 or an unaffected version
Follow official vendor advisories for update details
Review proxy configurations

Show the technical text from the sources

FreeRDP from 3.0.0-beta1 before 3.32.0 fails to enforce cumulative or absolute size limits when reassembling RDPDR channel fragments in the proxy. Attackers can send a FIRST fragment followed by continuation fragments without LAST, growing per-session heap streams proportional to traffic and exhausting proxy memory.
