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. (
