Technical Summary
This advisory covers 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), denial of service via buffer overflow and use-after-free (CVE-2026-23732, CVE-2026-24676), NULL pointer dereference (CVE-2026-23948), and arbitrary code execution via crafted RDP server messages (CVE-2026-31806). These vulnerabilities impact the FreeRDP client used in Red Hat Enterprise Linux Server 7 Extended Lifecycle Support. Red Hat has released updated packages to remediate these issues.
Potential Impact
The vulnerabilities include memory corruption issues such as heap-use-after-free and heap-buffer-overflow, which can lead to denial of service or potentially arbitrary code execution. The NULL pointer dereference can cause crashes. The arbitrary code execution vulnerability (CVE-2026-31806) allows execution of crafted RDP server messages, posing a significant risk. These issues could affect systems using vulnerable FreeRDP versions on Red Hat Enterprise Linux 7 Extended Lifecycle Support.
Mitigation Recommendations
Red Hat has released updated freerdp packages for Red Hat Enterprise Linux 7 Extended Lifecycle Support to address these vulnerabilities. Users should apply the security update as described in the Red Hat advisory RHSA-2026:11323 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official patches.
