edk2 vulnerabilities
Details

It was discovered that EDK II incorrectly handled CMS key unwrapping in the embedded OpenSSL library. An attacker could possibly use this issue to cause a heap buffer overflow, resulting in a denial of service. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2026-63072)

It was discovered that EDK II incorrectly handled CMP protection verification in the embedded OpenSSL library. An attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 24.04 LTS and Ubuntu 26.04 LTS. (CVE-2026-63076)

It was discovered that EDK II incorrectly buffered DTLS records in the embedded OpenSSL library. A remote attacker could possibly use this issue to cause EDK II to consume excessive memory, resulting in a denial of service. (CVE-2026-54874)

It was discovered that EDK II incorrectly verified AEAD tags in the embedded OpenSSL library. An attacker could possibly use this issue to cause EDK II to accept forged messages. This issue only affected Ubuntu 24.04 LTS and Ubuntu 26.04 LTS. (CVE-2026-75803)
