Original advisory details:
It was discovered that EDK II was susceptible to a predictable TCP Initial Sequence Number. An attacker could possibly use this issue to gain unauthorized access. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 24.04 LTS. (CVE-2023-45236, CVE-2023-45237)
It was discovered that EDK II incorrectly handled S3 sleep. An attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 24.04 LTS. (CVE-2024-1298)
It was discovered that the EDK II PE/COFF loader incorrectly handled certain memory operations. An attacker could possibly use this issue to cause a denial of service, obtain sensitive information, or execute arbitrary code. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 24.04 LTS. (CVE-2024-38796)
It was discovered that the EDK II PE image hashing function incorrectly handled certain memory operations. An attacker could possibly use this issue to cause a denial of service, or execute arbitrary code. (CVE-2024-38797)
It was discovered that the EDK II BIOS incorrectly handled certain memory operations. An attacker could possibly use this issue to cause a denial of service. (CVE-2024-38805, CVE-2025-2295)
It was discovered that EDK II incorrectly handled the enabling of MCE. An attacker could possibly use this issue to cause a denial of service, or execute arbitrary code. (CVE-2025-3770)
It was discovered that the OpenSSL library embedded in EDK II contained multiple vulnerabilties. An attacker could possibly use these issues to cause a denial of service, obtain sensitive information, or execute arbitrary code. (CVE-2021-3712, CVE-2022-0778, CVE-2022-4304, CVE-2022-4450, CVE-2023-0215, CVE-2023-0286, CVE-2023-0464, CVE-2023-0465, CVE-2023-0466, CVE-2023-2650, CVE-2023-3446, CVE-2023-3817, CVE-2023-5678, CVE-2023-6237, CVE-2024-0727, CVE-2024-13176, CVE-2024-2511, CVE-2024-41996, CVE-2024-4741, CVE-2024-5535, CVE-2024-6119, CVE-2024-9143, CVE-2025-9232)
