Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAn out-of-bounds read vulnerability exists in Samsung Notes when appending text to a paragraph. The vulnerability allows attackers to read memory outside the intended buffer boundaries due to insufficient bounds checking during text insertion operations. This could enable disclosure of sensitive information from the application's memory space.
