Technical Summary
This advisory covers five security vulnerabilities in FreeRDP affecting Red Hat Enterprise Linux 10 and related CodeReady Linux Builder variants. The issues include multiple heap-buffer-overflow flaws (CVE-2026-22853, CVE-2026-22855, CVE-2026-22859), a global-buffer-overflow (CVE-2026-22858), and a denial of service via use-after-free in ecam_channel_write (CVE-2026-24678). These vulnerabilities could potentially allow attackers to cause memory corruption or denial of service when using the xfreerdp client. Red Hat has issued updated freerdp packages to remediate these vulnerabilities.
Potential Impact
The vulnerabilities involve heap and global buffer overflows and a use-after-free condition, which can lead to memory corruption or denial of service. Exploitation could cause application crashes or potentially allow execution of arbitrary code, although no known exploits in the wild have been reported. The impact is rated as high by Red Hat Product Security.
Mitigation Recommendations
Red Hat has released updated freerdp packages for Red Hat Enterprise Linux 10 and related variants that address these vulnerabilities. Users should apply the security update as detailed in Red Hat advisory RHSA-2026:3068. For update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigations are specified by the vendor.
