CVE-2026-119341
Description
A flaw was found in Tesseract. The application is vulnerable to a Denial of Service (DoS) caused by memory corruption when processing pre-adapted template files with the legacy engine enabled. This issue occurs because raw data structures are loaded from template files without safely neutralizing internal pointer references before memory cleanup. An attacker who can supply or modify a template file can trigger the deallocation of arbitrary memory pointers, causing the application to crash.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Integrity,Availability,Confidentiality
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; Execute Unauthorized Code or Commands
This weakness may result in the corruption of memory, and perhaps instructions, possibly leading to a crash. If the corrupted memory can be effectively controlled, it may be possible to execute arbitrary code.
