CVE-2024-45775 Grub2: commands/extcmd: missing check for failed allocation

A flaw was found in grub2 where the grubextcmddispatcher function calls grubarglistalloc 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 parseoption function, leading...

CVE-2024-45775

CVE-2024-45775 concerns grub2: the function grub_extcmd_dispatcher() allocates memory for the grub argument list via grub_arg_list_alloc(), but does not handle allocation failure. If the allocation returns NULL, parse_option() dereferences a NULL pointer, causing grub to crash and, in rare cases,...

UBUNTU-CVE-2025-0686

A flaw was found in grub2. When performing a symlink lookup from a romfs filesystem, grub's romfs filesystem module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciously crafted...

CVE-2024-57258

CVE-2024-57258 affects Das U-Boot (pre-2025.01-rc1) with integer overflows in memory allocation. Exploitation can occur via a crafted squashfs filesystem (via sbrk or request2size) or due to mishandling ptrdiff_t on x86_64, leading to memory corruption. Connected advisories corroborate the issue ...
