Name of the Vulnerable Software and Affected Versions Dell Edge Gateway BIOS versions 3200 and 5200

Description The issue is related to an out-of-bounds write vulnerability in the System Management Mode (SMM) of the BIOS firmware. This could be exploited by a local authenticated malicious user with high privileges, potentially leading to arbitrary code execution or escalation of privilege. The vulnerability is associated with incorrect initialization of a resource.
