A security loophole involving an out-of-bounds read was identified in EDK2, the open-source reference implementation of the UEFI specification. This vulnerability enables an unauthorized attacker within the vicinity of the network to transmit a specifically crafted Neighbor Discovery Redirect message. Consequently, this may lead to the unauthorized reading of memory beyond the message boundaries, potentially resulting in the exposure of sensitive information.
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
