CVE-2026-111381

7.3High

Published 16 Oct 2026 · NVD status: Undergoing Analysis · AI triage by gemini-3.8-flash

7.3High

Attack vector: Local
Complexity: Low
Privileges needed: Low
User interaction: Required
Impact: Full C/I/A compromise
Weakness: CWE-122

Impact

A local attacker can crash FreeRDP or execute arbitrary code under the client user account. They need local file access and must convince a user to load a maliciously crafted persistent cache v2 file.

Root cause

An integer wraparound in bitmap size calculation inside persistent_cache_read_entry_v2 leads to mismatched entry size accounting and a heap buffer overflow during fixed 16 KiB reads.

Affected systems

FreeRDP prior to version 3.32.0

CVSS v3.1 · CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H

Fix & remediation

Upgrade FreeRDP to version 3.32.0 or later. If patching immediately is not possible, disable or avoid loading untrusted persistent cache files.

shell

$ sudo apt-get update && sudo apt-get install --only-upgrade freerdp3-x11

AI-suggested. Run it in staging first and check it against the vendor advisory. Why?

NVD description

FreeRDP before 3.32.0 contains a heap buffer overflow vulnerability in persistent_cache_read_entry_v2 that allows local attackers to corrupt heap memory via integer wraparound in bitmap size calculation. Attackers can craft a persistent cache v2 file with oversized width and height values that causes mismatched entry size accounting and fixed 16 KiB reads, leading to crashes or code execution when loaded.
