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 heap-use-after-free (CVE-2026-22856) * freerdp: FreeRDP heap-buffer-overflow (CVE-2026-22854) * freerdp: FreeRDP heap-buffer-overflow (CVE-2026-22852) * freerdp: FreeRDP: Denial of Service via FastGlyph parsing buffer overflow (CVE-2026-23732) * freerdp: FreeRDP: Denial of Service via use-after-free in AUDIN format renegotiation (CVE-2026-24676) * freerdp: FreeRDP has a heap-use-after-free in video_timer (CVE-2026-24491) * freerdp: FreeRDP has a NULL Pointer Dereference in rdp_write_logon_info_v2() (CVE-2026-23948) * freerdp: FreeRDP has a Heap-use-after-free in play_thread (CVE-2026-24684) * freerdp: FreeRDP has a heap-buffer-overflow in urb_select_interface (CVE-2026-24679) * freerdp: FreeRDP has a Heap-use-after-free in urb_select_interface (CVE-2026-24675) * freerdp: FreeRDP: Arbitrary code execution via crafted Remote Desktop Protocol (RDP) server messages (CVE-2026-31806) 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
The Red Hat security advisory RHSA-2026:10951 addresses multiple vulnerabilities in FreeRDP, including heap-use-after-free (CVE-2026-22856, CVE-2026-24491, CVE-2026-24675, CVE-2026-24684), heap-buffer-overflow (CVE-2026-22852, CVE-2026-22854, CVE-2026-24679), NULL pointer dereference (CVE-2026-23948), denial of service via buffer overflow and use-after-free (CVE-2026-23732, CVE-2026-24676), and arbitrary code execution (CVE-2026-31806) through crafted RDP server messages. These vulnerabilities affect the FreeRDP client used in Red Hat Enterprise Linux 8.6 variants. The advisory provides updated packages to remediate these issues. The CVSS scores are available on the respective CVE pages but are not included in the advisory. The vulnerabilities collectively pose risks including denial of service and potential arbitrary code execution.
Potential Impact
The vulnerabilities impact FreeRDP clients by enabling denial of service conditions through buffer overflows and use-after-free bugs, as well as potential arbitrary code execution via crafted RDP server messages. This could allow an attacker controlling an RDP server to execute code on the client system or disrupt client operations. The NULL pointer dereference may cause application crashes. The overall impact is rated as high by Red Hat Product Security.
Mitigation Recommendations
Red Hat has released updated FreeRDP packages for Red Hat Enterprise Linux 8.6 variants that address these vulnerabilities. Users should apply the security update RHSA-2026:10951 promptly to remediate these issues. Detailed update instructions are available at https://access.redhat.com/articles/11258. Since this is not a cloud service, remediation requires applying the vendor-provided patches. No indication of 'no action required' or 'already mitigated' is present, so patching is recommended.
