官方补丁披露时间
2022-06-07漏洞描述
A flaw was found in grub2 when handling IPv4 packets. This flaw allows an attacker to craft a malicious packet, triggering an integer underflow in grub code. Consequently, the memory allocation for handling the packet data may be smaller than the size needed. This issue causes an out-of-bands write during packet handling, compromising data integrity, confidentiality issues, a denial of service, and remote code execution.解决建议
建议您更新当前系统或软件至最新版，完成漏洞的修复。
