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.<\/p>\n<p>Severity: 4.8 | MEDIUM<\/p>\n<p>Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2025-61661 Published : Nov. 18, 2025, 6:20 p.m. | 44\u00a0minutes ago Description : A vulnerability has been identified in the GRUB (Grand Unified Bootloader) component.
