Red Hat Security Advisory: freerdp security update
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. The xfreerdp client can connect to RDP servers such as Microsoft Windows machines, xrdp, and VirtualBox. Security Fix(es): * freerdp: FreeRDP: Arbitrary code execution via heap out-of-bounds write in RLE planar decode path (CVE-2026-26965) * freerdp: FreeRDP: Arbitrary code execution via heap buffer overflow in GDI surface pipeline (CVE-2026-26955) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Technical Summary
Red Hat Product Security issued an advisory (RHSA-2026:6385) for FreeRDP, addressing two critical vulnerabilities: CVE-2026-26965, an arbitrary code execution vulnerability caused by a heap out-of-bounds write in the RLE planar decode path, and CVE-2026-26955, an arbitrary code execution vulnerability due to a heap buffer overflow in the GDI surface pipeline. These vulnerabilities could allow an attacker to execute arbitrary code on affected systems running FreeRDP clients. The advisory covers Red Hat Enterprise Linux 9.6 Extended Update Support and related CodeReady Linux Builder packages. Updated freerdp packages (version 2.11.7-1.el9_6.5) have been released to remediate these issues.
Potential Impact
Successful exploitation of these vulnerabilities could lead to arbitrary code execution on systems running vulnerable versions of FreeRDP. This poses a significant security risk as it may allow attackers to execute malicious code remotely. The advisory rates the security impact as Important (high severity). There are no known exploits in the wild at the time of the advisory.
Mitigation Recommendations
Red Hat has released updated freerdp packages that address these vulnerabilities. Users of affected Red Hat Enterprise Linux 9.6 Extended Update Support and related packages should apply the security update as detailed in the Red Hat advisory RHSA-2026:6385 and the referenced article https://access.redhat.com/articles/11258. Applying the official update is the recommended remediation. Patch status is confirmed as available via the vendor advisory.
