CVE-2024-57258: Integer overflows in memory allocation in Das U-Boot before 2025.01-rc1 occur for a crafted squashfs filesy...
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.
Security readout for executives and security teams
Plain-English summary
This is a high-severity bootloader weakness in Das U-Boot before 2025.01-rc1. A specially crafted SquashFS filesystem can trigger integer overflow during memory allocation, potentially affecting confidentiality, integrity, and availability. The practical attack path appears local or physical, so urgency is highest for embedded, appliance, and OT environments with exposed boot or update media.
Executive priority
Treat this as a high-priority firmware supply-chain and device-management issue, not a broad internet emergency. Focus on embedded and operational devices where physical access, update packages, or recovery media could be influenced.
Technical view
The CVE describes CWE-190 integer overflows in U-Boot allocation paths involving sbrk, request2size, and ptrdiff_t handling on x86_64 when processing crafted SquashFS content. CVSS 3.1 is 7.1 with physical attack vector, high complexity, no privileges, no user interaction, changed scope, and high CIA impact.
Likely exposure
Exposure is most likely in devices, firmware builds, or distributions using U-Boot before 2025.01-rc1 and parsing SquashFS during boot, recovery, or update workflows. Internet-facing exposure is not indicated by the supplied sources.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation. The CVSS vector indicates physical access and high attack complexity, suggesting exploitation is constrained but potentially serious where attackers can influence boot or update media.
Researcher notes
Evidence supports integer-overflow risk in SquashFS-related allocation handling, with architecture-specific mention of x86_64 ptrdiff_t behavior. The bundle does not provide exploit proof, affected downstream product completeness, or universal reachability details, so validation should be product- and firmware-specific.
Mitigation direction
Check vendor firmware advisories for affected U-Boot builds and fixed releases.
Upgrade to U-Boot 2025.01-rc1 or a vendor build containing the referenced fixes.
Prioritize appliances allowing removable boot, recovery, or local update media.
Apply Debian LTS or Siemens guidance where those products are in scope.
Restrict physical access and trusted update paths until firmware is remediated.
Validation and detection
Inventory products and firmware images that include Das U-Boot.
Confirm whether each build is before 2025.01-rc1 or lacks the referenced commits.
Identify boot, recovery, or update flows that parse SquashFS content.
Map Debian LTS and Siemens advisory applicability to deployed assets.
