暂无补丁情况
官方补丁披露时间
2022-09-23漏洞描述
There exists an unchecked length field in UBoot. The U-Boot DFU implementation does not bound the length field in USB DFU download setup packets, and it does not verify that the transfer direction corresponds to the specified command. Consequently, if a physical attacker crafts a USB DFU download setup packet with a `wLength` greater than 4096 bytes, they can write beyond the heap-allocated request buffer.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。
