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.

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.

ABB became aware of vulnerability in the product versions listed as affected in the advisory. An update is now available that addresses and remediates the vulnerability.

A network attacker could exploit the vulnerabilities to execute remote code, initiate DoS attacks, conduct DNS cache poisoning, or extract sensitive information.
