Exploitation evidence

Disclosed: evidence found.
CVE published 2 Nov 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 3 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Apply the official security update provided by Red Hat for FreeRDP version 2:2.11.7-7.el9_8.9 or later. This update addresses CVE-2026-109242 and related denial of service vulnerabilities. No additional mitigation steps are required beyond installing the vendor-supplied patch.

Description

FreeRDP, a free implementation of the Remote Desktop Protocol client, contains a denial of service vulnerability due to uninitialized progressive tile handling (CVE-2026-109242). This issue can cause the application to crash or become unresponsive. The vulnerability affects versions prior to 2:2.11.7-7.el9_8.9. A security update addressing this and other denial of service flaws in FreeRDP has been released by Red Hat.

Impact

Successful exploitation of this vulnerability results in denial of service conditions, causing the FreeRDP client to crash or become unresponsive. This disrupts remote desktop connectivity but does not indicate code execution or data compromise based on the provided information.

Summary

CVE-2026-109242 is a denial of service vulnerability in FreeRDP caused by uninitialized progressive tile handling in the xfreerdp client. This flaw can lead to application crashes or hangs when processing RDP sessions. The vulnerability affects FreeRDP versions before 2:2.11.7-7.el9_8.9. Red Hat has issued an important security update fixing this issue along with other denial of service vulnerabilities in FreeRDP, including heap-based buffer overflow during MP3 audio decoding and heap out-of-bounds write in NTLM authentication.
