CVE-2022-36763
EDK2 is susceptible to a vulnerability in the Tcg2MeasureGptTable() function, allowing a user to trigger a heap buffer overflow via a local network. Successful exploitation of this vulnerability may result in a compromise of confidentiality, integrity, and/or availability.
CVE-2022-36764
EDK2 is susceptible to a vulnerability in the Tcg2MeasurePeImage() function, allowing a user to trigger a heap buffer overflow via a local network. Successful exploitation of this vulnerability may result in a compromise of confidentiality, integrity, and/or availability.
CVE-2022-36765
EDK2 is susceptible to a vulnerability in the CreateHob() function, allowing a user to trigger a integer overflow to buffer overflow via a local network. Successful exploitation of this vulnerability may result in a compromise of confidentiality, integrity, and/or availability.
CVE-2023-45229
EDK2's Network Package is susceptible to an out-of-bounds read vulnerability when processing the IA_NA or IA_TA option in a DHCPv6 Advertise message. This vulnerability can be exploited by an attacker to gain unauthorized access and potentially lead to a loss of Confidentiality.
CVE-2023-45231
EDK2's Network Package is susceptible to an out-of-bounds read vulnerability when processing  Neighbor Discovery Redirect message. This vulnerability can be exploited by an attacker to gain unauthorized access and potentially lead to a loss of Confidentiality.
CVE-2023-45232
EDK2's Network Package is susceptible to an infinite loop vulnerability when parsing unknown options in the Destination Options header of IPv6. This vulnerability can be exploited by an attacker to gain unauthorized access and potentially lead to a loss of Availability.
CVE-2023-45233
EDK2's Network Package is susceptible to an infinite lop vulnerability when parsing a PadN option in the Destination Options header of IPv6. This vulnerability can be exploited by an attacker to gain unauthorized access and potentially lead to a loss of Availability.
CVE-2023-45235
EDK2's Network Package is susceptible to a buffer overflow vulnerability when handling Server ID option from a DHCPv6 proxy Advertise message. This vulnerability can be exploited by an attacker to gain unauthorized access and potentially lead to a loss of Confidentiality, Integrity and/or Availability.
