CVE-2024-45775 (GCVE-0-2024-45775)

Vulnerability from cvelistv5 – Published: 2025-02-18 19:25 – Updated: 2025-11-20 19:06
VLAI?
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.
