Description OSIDB Bzimport 2025-01-13 23:11:03 UTC 
In grub_extcmd_dispatcher() function grub2 calls grub_arg_list_alloc() to allocate memory for the grub's argument list, however it misses to check in case the memory allocation failed. Once the allocation failed, a NULL point will be processed by the parse_option() function leading grub to crash or in some rare scenarios corrupt the IVT data.
