21
FAUCET Score

CVE-2019-19624 is an out-of-bounds read vulnerability in OpenCV versions prior to 4.1.1, specifically within the calc()/ocl_calc() functions in dis_flow.cpp, affecting products like Red Hat Enterprise Linux. This flaw arises when processing small images, causing incorrect variable assumptions and leading to an out-of-bounds read from heap-allocated arrays. Rated Medium (CVSS 6.5), it presents a low impact on confidentiality and availability, with no user interaction required for exploitation. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion, and it is not listed in CISA's KEV catalog.
