CVE-2024-34622

Local code execution via paragraph append overflow

Published Aug 7, 2024 · Updated Aug 7, 2024

Out-of-bounds write in Samsung Notes before 4.4.21.62 allows local users to execute code with Samsung Notes privileges. The paragraph-appending path writes beyond its intended buffer because affected builds lack the input validation added by the patch. Exploitation requires low-privileged local access, and successful memory corruption can compromise data and availability within the application's security context.
