CVE-2025-53644 – GHSL-2025-057 - OpenCV contains a use after free buffer write due to an uninitialized pointer
https://notcve.org/view.php?id=CVE-2025-53644
17 Jul 2025 — OpenCV is an Open Source Computer Vision Library. Versions prior to 4.12.0 have an uninitialized pointer variable on stack that may lead to arbitrary heap buffer write when reading crafted JPEG images. Version 4.12.0 fixes the vulnerability. • https://github.com/opencv/opencv/commit/a39db41390de546d18962ee1278bd6dbb715f466 • CWE-457: Use of Uninitialized Variable •

CVE-2019-19624
https://notcve.org/view.php?id=CVE-2019-19624
06 Dec 2019 — An out-of-bounds read was discovered in OpenCV before 4.1.1. Specifically, variable coarsest_scale is assumed to be greater than or equal to finest_scale within the calc()/ocl_calc() functions in dis_flow.cpp. However, this is not true when dealing with small images, leading to an out-of-bounds read of the heap-allocated arrays Ux and Uy. Se detectó una lectura fuera de límites en OpenCV versiones anteriores a 4.1.1. Específicamente, una variable coarsest_scale es asumida para ser mayor o igual que finest_s... • https://access.redhat.com/security/cve/cve-2019-19624 • CWE-125: Out-of-bounds Read •
