CVE-2025-61661 (CNNVD-202511-1987)
中文标题:
GNU GRUB 安全漏洞
英文标题:
Grub2: grub2: out-of-bounds write via malicious usb device
漏洞描述
中文描述:
GNU GRUB是GNU社区的一款Linux系统引导程序。 GNU GRUB存在安全漏洞，该漏洞源于USB设备字符串转换处理不当，可能导致拒绝服务或数据损坏。
英文描述:
A vulnerability has been identified in the GRUB (Grand Unified Bootloader) component. This flaw occurs because the bootloader mishandles string conversion when reading information from a USB device, allowing an attacker to exploit inconsistent length values. A local attacker can connect a maliciously configured USB device during the boot sequence to trigger this issue. A successful exploitation may lead GRUB to crash, leading to a Denial of Service. Data corruption may be also possible, although given the complexity of the exploit the impact is most likely limited.
