CVE-2026-88054

A flaw was found in Tesseract, an open-source Optical Character Recognition OCR engine. A remote attacker could provide a specially crafted '.traineddata' model with a zero-length stack for certain internal layers. This would cause an empty-stack dereference during model loading, leading to a...

CVE-2026-88054

Tesseract is an open-source OCR engine affected in version 5.5.3 and earlier by a denial-of-service flaw. The root cause is in Plumbing::DeSerialize (src/lstm/plumbing.cpp), which rejects excessively large network stacks but accepts a zero-length stack for NT_SERIES, NT_PARALLEL, or NT_REVERSED l...

CVE-2026-88054 Tesseract: Denial of service via empty-stack dereference in Plumbing/Series at model load

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, Plumbing::DeSerialize in src/lstm/plumbing.cpp rejects excessively large network stacks but accepts a zero-length stack for NTSERIES, NTPARALLEL, or NTREVERSED layers in a crafted .traineddata model. During LSTMRecognizer...
