CVE-2025-2296
HighCVSS 8.4Exploitation Probability (EPSS)
Elevated risk54th percentile - higher than 54% of all known CVEs
Summary
EDK2 contains a vulnerability in BIOS where an attacker with local access may cause 'Improper Input Validation'. Successful exploitation could alter control flow unexpectedly, potentially allowing arbitrary command execution and impacting Confidentiality, Integrity, and Availability.
Risk Assessment
A local attacker may gain the ability to execute arbitrary code in BIOS, potentially leading to full system compromise, affecting confidentiality, integrity, and availability.
Recommendation
Apply patches provided by EDK2 vendor or motherboard manufacturer to fix the vulnerability.
Other vulnerabilities in EDK2
See all- CVE-2026-97631Critical
EDK2 contains a vulnerability in BIOS where a user may cause an out-of-bounds write, classic buffer overflow, and incorrect calculation of buffer size via remote access. Successful exploitation can lead to arbitrary code execution. It could also impact confidentiality, integrity, and availability.
- CVE-2024-38798Medium
EDK2 contains a vulnerability in BIOS where an attacker may cause 'Exposure of Sensitive Information to an Unauthorized Actor' by local access. Successful exploitation may lead to information disclosure or privilege escalation and impact confidentiality.
- CVE-2025-2486High
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.
Original NVD description (English source)
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.
