FKIE_CVE-2024-45775

Vulnerability from fkie_nvd - Published: 2025-02-18 20:15 - Updated: 2025-05-13 20:15
Severity ?
5.2 (Medium) - CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:H
Summary
A flaw was found in grub2 where the grub_extcmd_dispatcher() function calls grub_arg_list_alloc() to allocate memory for the grub's argument list. However, it fails to check in case the memory allocation fails. Once the allocation fails, a NULL point will be processed by the parse_option() function, leading grub to crash or, in some rare scenarios, corrupt the IVT data.
