CVE-2025-0678
|
| VCID-3eq9-kvj5-jya2 | grub2: read: Integer overflow may lead to out-of-bounds write |
CVE-2025-0690
|
| VCID-3hgd-6nhb-qbfu | grub2: reiserfs: Integer overflow when handling symlinks may lead to heap based out-of-bounds write when reading data |
CVE-2025-0684
|
| VCID-3y7s-y777-9bce | grub2: UFS: Integer overflow may lead to heap based out-of-bounds write when handling symlinks |
CVE-2025-0677
|
| VCID-5a9t-t1gk-j7ba | grub2: jfs: Integer overflow when handling symlinks may lead to heap based out-of-bounds write when reading data |
CVE-2025-0685
|
| VCID-5mbv-3pzx-9fdf | A flaw was found in grub2. When reading a symbolic link's name from a UFS filesystem, grub2 fails to validate the string length taken as an input. The lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and eventually allowing an attacker to circumvent secure boot protections. |
CVE-2024-45781
|
| VCID-5msw-szj7-efg6 | A stack overflow flaw was found when reading a BFS file system. A crafted BFS filesystem may lead to an uncontrolled loop, causing grub2 to crash. |
CVE-2024-45778
|
| VCID-5v25-3fq8-hbh7 | A flaw was found in grub2. When reading tar files, grub2 allocates an internal buffer for the file name. However, it fails to properly verify the allocation against possible integer overflows. It's possible to cause the allocation length to overflow with a crafted tar file, leading to a heap out-of-bounds write. This flaw eventually allows an attacker to circumvent secure boot protections. |
CVE-2024-45780
|
| VCID-8vm3-vfkx-x3ay | grub2: fs/hfs: Integer overflow may lead to heap based out-of-bounds write |
CVE-2025-1125
|
| VCID-c63e-ytnu-hqcn | A flaw was found in grub2. When failing to mount an HFS+ grub, the hfsplus filesystem driver doesn't properly set an ERRNO value. This issue may lead to a NULL pointer access. |
CVE-2024-45783
|
| VCID-f7zs-5hu5-7kgq | grub2: heap-based buffer overflow |
CVE-2024-56737
|
| VCID-g8dt-5s5d-2kaa | grub2: net: Out-of-bounds write in grub_net_search_config_file() |
CVE-2025-0624
|
| VCID-ht6b-33up-4qfv | grub2: udf: Heap based buffer overflow in grub_udf_read_block() may lead to arbitrary code execution |
CVE-2025-0689
|
| VCID-m97u-13fq-jfbw | grub2: commands/dump: The dump command is not in lockdown when secure boot is enabled |
CVE-2025-1118
|
| VCID-mfx5-q1cr-rbgb | grub2: romfs: Integer overflow when handling symlinks may lead to heap based out-of-bounds write when reading dat |
CVE-2025-0686
|
| VCID-q4z6-cp3e-tfg4 | A flaw was found in grub2. A specially crafted JPEG file can cause the JPEG parser of grub2 to incorrectly check the bounds of its internal buffers, resulting in an out-of-bounds write. The possibility of overwriting sensitive information to bypass secure boot protections is not discarded. |
CVE-2024-45774
|
| VCID-qdpn-t7u4-h7c8 | An integer overflow flaw was found in the BFS file system driver in grub2. When reading a file with an indirect extent map, grub2 fails to validate the number of extent entries to be read. A crafted or corrupted BFS filesystem may cause an integer overflow during the file reading, leading to a heap of bounds read. As a consequence, sensitive data may be leaked, or grub2 will crash. |
CVE-2024-45779
|
| VCID-qfa6-cdfg-wffs | grub2: command/gpg: Use-after-free due to hooks not being removed on module unload |
CVE-2025-0622
|
| VCID-smxq-995q-rqca | A flaw was found in the HFS filesystem. When reading an HFS volume's name at grub_fs_mount(), the HFS filesystem driver performs a strcpy() using the user-provided volume name as input without properly validating the volume name's length. This issue may read to a heap-based out-of-bounds writer, impacting grub's sensitive data integrity and eventually leading to a secure boot protection bypass. |
CVE-2024-45782
|
| VCID-suzk-agp2-hqc3 | A flaw was found in grub2. The calculation of the translation buffer when reading a language .mo file in grub_gettext_getstr_from_position() may overflow, leading to a Out-of-bound write. This issue can be leveraged by an attacker to overwrite grub2's sensitive heap data, eventually leading to the circumvention of secure boot protections. |
CVE-2024-45777
|
| VCID-ue6k-w2p8-uyeb | When reading the language .mo file in grub_mofile_open(), grub2 fails to verify an integer overflow when allocating its internal buffer. A crafted .mo file may lead the buffer size calculation to overflow, leading to out-of-bound reads and writes. This flaw allows an attacker to leak sensitive data or overwrite critical data, possibly circumventing secure boot protections. |
CVE-2024-45776
|
| VCID-zgpm-nx21-7bb4 | 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. |
