What is CVE-2026-22770?

ImageMagick, a widely used open-source software for image processing, contains a vulnerability related to the BilateralBlurImage method. In versions before 7.1.2-13, the last element of a set of double buffers allocated during the AcquireBilateralTLS process is not properly initialized. This flaw can lead to the release of an invalid pointer in the DestroyBilateralTLS function when memory allocation fails, potentially allowing attackers to exploit this condition and disrupt normal operations.
