It was discovered that FreeRDP incorrectly handled memory under certain circumstances, which could lead to a NULL pointer dereference. An attacker could possibly use this issue to cause a denial of service. (CVE-2026-23948) It was discovered that FreeRDP did not correctly validate the size of certain variables, which could cause a buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected FreeRDP3 in Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2026-24491) It was discovered that FreeRDP did not correctly validate the size of certain variables, which could cause a buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2026-24675, CVE-2026-24679, CVE-2026-24682) It was discovered that FreeRDP had a use after free vulnerability under certain circumstances. An attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2026-24676, CVE-2026-24681) It was discovered that FreeRDP did not correctly validate the size of certain variables, which could cause a buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 25.10. (CVE-2026-24677) It was discovered that FreeRDP had a use after free vulnerability under certain circumstances.
