CVE-2023-40238: A LogoFAIL issue was discovered in BmpDecoderDxe in Insyde InsydeH2O with kernel 5.2 before 05.28.47, 5.3 before 05.37.47, 5.4 before 05.45.

Noroxi assessment

Priority: Monitor (action score 23/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.8% (FIRST EPSS); higher than 78.9% of all records.
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

A LogoFAIL issue was discovered in BmpDecoderDxe in Insyde InsydeH2O with kernel 5.2 before 05.28.47, 5.3 before 05.37.47, 5.4 before 05.45.47, 5.5 before 05.53.47, and 5.6 before 05.60.47 for certain Lenovo devices. Image parsing of crafted BMP logo files can copy data to a specific address during the DXE phase of UEFI execution. This occurs because of an integer signedness error involving PixelHeight and PixelWidth during RLE4/RLE8 compression.
