CVE-2024-22211

CWE-122Published: January 19, 2024· Updated: Jun 17, 2026

9.8
CVSS v3.1

Official Description

FreeRDP is a set of free and open source remote desktop protocol library and clients. In affected versions an integer overflow in `freerdp_bitmap_planar_context_reset` leads to heap-buffer overflow. This affects FreeRDP based clients. FreeRDP based server implementations and proxy are not affected. A malicious server could prepare a `RDPGFX_RESET_GRAPHICS_PDU` to allocate too small buffers, possibly triggering later out of bound read/write. Data extraction over network is not possible, the buffers are used to display an image. This issue has been addressed in version 2.11.5 and 3.2.0. Users are advised to upgrade. there are no know workarounds for this vulnerability.

Risk Analysis

FreeRDP contains an integer overflow in the bitmap planar context reset function, which can lead to a heap-buffer overflow. This flaw allows a malicious server to trigger memory corruption in connected clients, warranting a critical severity rating.

No public exploit is currently known, and the vulnerability is not in the KEV catalog. It is remotely exploitable with low attack complexity.

Recommended Action

Upgrade FreeRDP clients to version 2.11.5 or 3.2.0 to address the overflow issue.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2024-22211 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
