## Affected

- libyal libesedb: through 20260704

## Description

Libyal libesedb through 20260704 contains a heap out-of-bounds read vulnerability in libesedb_record_get_multi_value() that allows attackers to read past buffers via unbounded multi-value offset tables. Attackers can supply a crafted ESE/EDB database processed by esedbexport to crash the application or expose up to about 32 KiB of adjacent heap memory.
