CVE-2026-88053

A flaw was found in Tesseract, an open-source Optical Character Recognition OCR engine. A local attacker could provide a specially crafted .traineddata file, which, when processed, could lead to a heap out-of-bounds write. This vulnerability occurs due to unvalidated counts used as loop bounds...

CVE-2026-88051

A flaw was found in Tesseract, an open-source Optical Character Recognition OCR engine.
