CVE-2024-45775
MEDIUMRed Hat Enterprise Linux 9 - Denial of Service via NULL Pointer Dereference in grub_extcmd_dispatcher
Title source: llmDescription
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.
