| CVE-2026-33243 | barebox is a bootloader. In barebox from version 2016.03.0 to before version 2026.03.1 (and the corresponding backport to 2025.09.3), an attacker could exploit a FIT signature verification vulnerability to trick the bootloader into booting different images than those that were verified as part of a signed configuration. mkimage(1) sets the hashed-nodes property of the FIT signature node to list which nodes of the FIT were hashed as part of the signing process as these will need to be verified la | [email protected] | 8.2 | 0.11% | 2026-03-20 | 2026-06-17 |

| CVE-2024-57259 | sqfs_search_dir in Das U-Boot before 2025.01-rc1 exhibits an off-by-one error and resultant heap memory corruption for squashfs directory listing because the path separator is not considered in a size calculation. | [email protected] | 7.1 | 0.36% | 2025-02-18 | 2026-06-17 |
| CVE-2024-57258 | Integer overflows in memory allocation in Das U-Boot before 2025.01-rc1 occur for a crafted squashfs filesystem via sbrk, via request2size, or because ptrdiff_t is mishandled on x86_64. | [email protected] | 7.1 | 0.23% | 2025-02-18 | 2026-06-17 |
| CVE-2024-57257 | A stack consumption issue in sqfs_size in Das U-Boot before 2025.01-rc1 occurs via a crafted squashfs filesystem with deep symlink nesting. | [email protected] | 2.0 | 0.31% | 2025-02-18 | 2026-06-17 |
| CVE-2024-57256 | An integer overflow in ext4fs_read_symlink in Das U-Boot before 2025.01-rc1 occurs for zalloc (adding one to an le32 variable) via a crafted ext4 filesystem with an inode size of 0xffffffff, resulting in a malloc of zero and resultant memory overwrite. | [email protected] | 7.1 | 0.36% | 2025-02-18 | 2026-06-17 |
| CVE-2024-57255 | An integer overflow in sqfs_resolve_symlink in Das U-Boot before 2025.01-rc1 occurs via a crafted squashfs filesystem with an inode size of 0xffffffff, resulting in a malloc of zero and resultant memory overwrite. | [email protected] | 7.1 | 0.36% | 2025-02-18 | 2026-06-17 |

| CVE-2024-42040 | Buffer Overflow vulnerability in the net/bootp.c in DENEX U-Boot from its initial commit in 2002 (3861aa5) up to today on any platform allows an attacker on the local network to leak memory from four up to 32 bytes of memory stored behind the packet to the network depending on the later use of DHCP-provided parameters via crafted DHCP responses. | [email protected] | 8.1 | 0.60% | 2024-08-23 | 2026-06-17 |
