Pengutronix Barebox

CVE-2019-15937

Pengutronix barebox up to 2019.08.1 is affected by a remote buffer overflow in nfs_readlink_reply (net/nfs.c) caused by a length field being used directly in a memcpy. Affected product: Pengutronix barebox; vulnerable component: net/nfs.c (nfs_readlink_reply). The CVE details report a high-severi...

CVE-2021-37847

CVE-2021-37847 affects Pengutronix barebox up to version 2021.07.0, where crypto/digest.c leaks timing information during digest verification because memcmp is used. The connected documents confirm the same description across NVD/Red Hat/OSV/CVE lists and related sources, with no details on concr...

CVE-2021-37848

Pengutronix barebox (through 2021.07.0) is affected by CVE-2021-37848 due to a timing leak in common/password.c during hash comparison (strncmp). This is a timing-side-channel vulnerability in the bootloader used in embedded Linux systems. Affected component: barebox binary; issue arises from str...

CVE-2026-46728

The CVE-2026-46728 entry concerns U-Boot (before 2026.04) where FIT (Flat Image Tree) signature verification can bypass trust because hashed-nodes are omitted from a hash. Affected software: U-Boot (pre-2026.04). Vulnerable component: FIT signature verification process. Root cause: omission of ha...

CVE-2026-34963

Barebox EFI PE loader (efi/loader/pe.c) contains multiple memory-safety vulnerabilities in versions prior to 2026.04.0: (1) 32-bit arithmetic overflow in virtual image size calculation on section VirtualAddress/size can cause undersized heap allocations, and (2) PE section loading does not valida...

CVE-2019-15938

Pengutronix barebox (through 2019.08.1) is affected by a remote buffer overflow in nfs_readlink_req (fs/nfs.c), where a length field is directly used in memcpy. This root cause enables an overflow over the network vector, with CVSS data indicating high/critical impact (network attack, no user int...

CVE-2026-33243

Barebox contains a vulnerability in the FIT signing flow: during mkimage, the hashed-nodes property of the FIT signature node is computed, but the hashed-nodes value is not itself protected by the hash. An attacker can modify hashed-nodes to influence which nodes were reported as hashed, potentia...

CVE-2026-34961

Barebox before 2026.04.0 has a heap out-of-bounds read in ext4 extent parsing due to missing validation of eh_entries against buffer capacity in fs/ext4/ext4_common.c. An attacker could supply a malicious ext4 image over USB, SD card, or network boot to trigger reads beyond the allocated buffer d...

CVE-2026-34962

CVE-2026-34962 affects barebox prior to 2026.04.0, where a vulnerability in ext4 directory parsing (fs/ext4/ext4_common.c) allows an infinite loop during directory listing or path resolution. The root cause is that ext4fs_iterate_dir() does not validate non-zero directory entry lengths, so a craf...

CVE-2026-34960

barebox before 2026.04.0 contains an out-of-bounds read in DHCP option parsing (dhcp_message_type) due to not ensuring the options pointer stays within packet bounds. An attacker on the same broadcast domain can send a crafted DHCP Offer/ACK lacking a proper 0xff end marker to cause the parser to...
