CVE-2024-45775

Summary

CVE-2024-45775 is a vulnerability affecting the grub2 bootloader. The issue lies in the grub_extcmd_dispatcher() function, which calls grub_arg_list_alloc() to allocate memory for the grub argument list. If this memory allocation fails, grub processes a NULL pointer instead. This leads grub to crash or, in rare cases, corrupt the Interrupt Vector Table (IVT) data. The vulnerability can potentially allow an attacker to gain unauthorized control over the system during boot time. It is essential to apply the necessary patches to mitigate this risk.
