Summary
u-boot vulnerabilities
Details
Timo Preißl discovered that U-Boot incorrectly handled certain malformed ZFS file system metadata. An attacker could possibly use this issue to trigger an integer overflow and out-of-bounds memory access, resulting in arbitrary code execution or a denial of service. (CVE-2025-70290)
Timo Preißl discovered that U-Boot incorrectly calculated buffer sizes when processing certain ext4 file systems. An attacker could possibly use this issue to trigger an integer overflow and out-of-bounds memory access, resulting in arbitrary code execution or a denial of service. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2025-70293)
Mateusz Furdyna discovered that U-Boot incorrectly handled certain fragmented IP traffic when IP defragmentation was enabled. An attacker could possibly use this issue to corrupt memory by sending crafted IP fragments, resulting in arbitrary code execution. (CVE-2026-15390)
Shahriyar Jalayeri and Mehrun P. Hunter discovered that U-Boot incorrectly handled certain fragmented IP traffic during network boot when IP defragmentation was enabled. An attacker could possibly use this issue to trigger an out-of-bounds write, resulting in a denial of service. (CVE-2026-71971)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
