NetworkPkg/IScsiDxe has remotely exploitable buffer overflows.

Use after free vulnerability in EDK II may allow an authenticated user to potentially enable escalation of privilege, information disclosure and/or denial of service via adjacent access.

A BIOS bug in firmware for a particular PC model leaves the Platform authorization value empty. This can be used to permanently brick the TPM in multiple ways, as well as to non-permanently DoS the system.

Integer truncation in EDK II may allow an authenticated user to potentially enable escalation of privilege via local access.

Integer overflow in the Drive Execution Environment (DXE) phase in the Capsule Update feature in the UEFI implementation in EDK2 allows physically proximate attackers to bypass intended access restrictions via crafted data.

Multiple integer overflows in the Pre-EFI Initialization (PEI) boot phase in the Capsule Update feature in the UEFI implementation in EDK2 allow physically proximate attackers to bypass intended access restrictions by providing crafted data that is not properly handled during the coalescing phase.

Buffer overflow in the Reclaim function in Tianocore EDK2 before SVN 16280 allows physically proximate attackers to gain privileges via a long variable name.

A heap overflow in LzmaUefiDecompressGetInfo function in EDK II.

An insecure default to allow UEFI Shell in EDK2 was left enabled in Ubuntu's EDK2. This allows an OS-resident attacker to bypass Secure Boot.

An insecure default to allow UEFI Shell in EDK2 was left enabled in LXD. This allows an OS-resident attacker to bypass Secure Boot.
