Special notes on CVE-2026-111272

Submitted by lexa on

  • (as described on author's page): This CVE report is based "only on static analysis" without attempting to reproduce the issue at runtime.
  • In fact, "static analysis" failed: it assumes system calloc() use for memory allocation while LibRaw::calloc() is used in reality.
  • So, "discovered" OOB-heap accesses by fixed offset(s) are not OOB, all accesses occur within the allocated buffer
  • The author made no attempts to contact our team.
  • Our attempts to contact him also went unanswered.
