Loading vulnerability…
CVE-2026-62356 is a memory corruption vulnerability in Redis caused by an incorrectly calculated buffer size while loading RDB data. The flaw occurs during RDB parsing/loading and can result in writes beyond the bounds of a heap-allocated buffer. This is a classic heap-based out-of-bounds write condition triggered by malformed or maliciously crafted RDB input. Because the vulnerable condition arises during deserialization/loading of database state, successful exploitation may destabilize the process and, depending on allocator behavior and surrounding memory layout, may create a path toward code execution.
