EDK2 contains a vulnerability in BIOS where a user may cause “Out-of-bounds
Write”, Classic
Buffer Overflow, and “Incorrect Calculation of Buffer Size” by remote access. Successful exploitation of this vulnerability
can lead to arbitrary
code execution. It could also impact
Confidentiality,
Integrity,
and Availability.
Un-verified kernel bypass Secure Boot mechanism in direct boot mode
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.

Uncleared password keystrokes in circular queue can lead to information disclosure or escalation of privilege
EDK2 contains a vulnerability in BIOS where an attacker may cause “Exposure of Sensitive Information to an Unauthorized Actor” by local access. Successful exploitation of this vulnerability will lead to
possible information disclosure or escalation of privilege
and impact Confidentiality.
UEFI Shell accessible in AAVMF with Secure Boot enabled on Ubuntu
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.
iSCSI Remote Memory Corruption and Denial of Service
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.
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.
EDK2 contains a vulnerability in the HashPeImageByType(). A user may cause a read out of bounds when a corrupted data pointer and length are sent via an adjecent network. A successful exploit of this vulnerability may lead to a loss of Integrity and/or Availability.
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.
Timing side-channel in ECDSA signature computation
Issue summary: A timing side-channel which could potentially allow recovering
the private key exists in the ECDSA signature computation.
Impact summary: A timing side-channel in ECDSA signature computations
could allow recovering the private key by an attacker. However, measuring
the timing would require either local access to the signing application or
a very fast network connection with low latency.
There is a timing signal of around 300 nanoseconds when the top word of
the inverted ECDSA nonce value is zero. This can happen with significant
probability only for some of the supported elliptic curves. In particular
the NIST P-521 curve is
EDK2 contains a vulnerability in the PeCoffLoaderRelocateImage(). An Attacker may cause memory corruption due to an overflow via an adjacent network. A successful exploit of this vulnerability may lead to a loss of Confidentiality, Integrity, and/or Availability.
Integer Overflow caused by divide by zero during S3 suspension
EDK2 contains a vulnerability when S3 sleep is activated where an Attacker may cause a Division-By-Zero due to a UNIT32 overflow via local access. A successful exploit of this vulnerability may lead to a loss of Availability.
