CVE-2026-88053 is a high-severity heap out-of-bounds write vulnerability in the open source OCR engine Tesseract, affecting version 5.5.3 and earlier. The flaw occurs in the Classify::ReadIntTemplates function when processing crafted .traineddata files, where certain counts are used as loop bounds without proper validation. This can lead to heap corruption, crashes, or potentially controlled memory corruption during legacy-classifier initialization before OCR processing starts. No official fix or patch is available as of the latest review.
