An unlimited recursion in DxeCore in EDK II.CVE-2025-2296debianedk2+10EPSS score0.77%
EDK2 contains a vulnerability in BIOS where an attacker may cause “ Improper Input Validation” by local access. Successful exploitation of this vulnerability could alter control flow in unexpected ways, potentially allowing arbitrary command execution and impacting Confidentiality, Integrity, and Availability.CVE-2025-2295debianedk2+2EPSS score0.24%
EDK2 contains a vulnerability in BIOS where a user may cause an Integer Overflow or Wraparound by network means. A successful exploitation of this vulnerability may lead to denial of service.CVE-2025-2486debianedk2+3EPSS score0.13%
The Ubuntu edk2 UEFI firmware packages accidentally allowed the UEFI Shell to be accessed in Secure Boot environments, possibly allowing bypass of Secure Boot constraints. Versions 2024.05-2ubuntu0.3 and 2024.02-2ubuntu0.3 disable the Shell. Some previous versions inserted a secure-boot-based decision to continue running inside the Shell itself, which is believed to be sufficient to enforce Secure Boot restrictions. This is an additional repair on top of the incomplete fix for CVE-2023-48733.CVE-2025-3770debianedk2+2EPSS score0.15%
EDK2 contains a vulnerability in BIOS where an attacker may cause “Protection Mechanism Failure” by local access. Successful exploitation of this vulnerability will lead to arbitrary code execution and impact Confidentiality, Integrity, and Availability.CVE-2014-4859american megatrends incorporated (ami)bios+3EPSS score0.59%
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.CVE-2014-4860american megatrends incorporated (ami)bios+3EPSS score0.50%
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.
