Grub2: fs/ufs: 堆内存中OOB写漏洞
漏洞描述信息
在grub2中发现了一个漏洞。当从UFS文件系统读取符号链接的名称时,grub2未能验证作为输入的字符串长度。这种验证的缺失可能导致堆溢出写入,从而引发数据完整性问题,并最终使攻击者能够绕过安全启动保护。

漏洞标题
Grub2: fs/ufs: oob write in the heap
漏洞描述信息
A flaw was found in grub2. When reading a symbolic link's name from a UFS filesystem, grub2 fails to validate the string length taken as an input. The lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and eventually allowing an attacker to circumvent secure boot protections.
