An attacker on thelocal network could potentially use this to impact availability or possiblycause remote code execution. (CVE-2022-36763, CVE-2022-36764,CVE-2022-36765)It was discovered that a buffer overflows exists in EDK2's Network PackageAn attacker on the local network could potentially use these to impactavailability or possibly cause remote code execution. (CVE-2023-45230,CVE-2023-45234, CVE-2023-45235)It was discovered that an out-of-bounds read exists in EDK2's NetworkPackage An attacker on the local network could potentially use this toimpact confidentiality. (CVE-2023-45231)It was discovered that infinite-loops exists in EDK2's Network PackageAn attacker on the local network could potentially use these to impactavailability. (CVE-2023-45232, CVE-2023-45233)Mate Kukri discovered that an insecure default to allow UEFI Shell inEDK2 was left enabled in Ubuntu's EDK2. An attacker could use this tobypass Secure Boot.
