{"schemaVersion":3,"id":"CVE-2025-61661","aliases":["UBUNTU-CVE-2025-61661","DEBIAN-CVE-2025-61661"],"status":"published","duplicateOf":null,"title":null,"description":"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.","dates":{"published":"2025-11-18T18:20:42.151Z","modified":"2026-09-01T11:53:52.929Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":4.8,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:P/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":4.8,"severity":"medium","vector":"CVSS:3.1/AV:P/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
