Hi, The following vulnerability was published for lmdb. CVE-2026-22185[0]: | OpenLDAP Lightning Memory-Mapped Database (LMDB) versions up to and | including 0.9.14, prior to commit 8e1fda8, contain a heap buffer | underflow in the readline() function of mdb_load. When processing | malformed input containing an embedded NUL byte, an unsigned offset | calculation can underflow and cause an out-of-bounds read of one | byte before the allocated heap buffer. This can cause mdb_load to | crash, leading to a limited denial-of-service condition. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
