With memory-mapped files, it has the read performance of a pure in-memory database while retaining the persistence of standard disk-based databases.\r\n\r\nSecurity Fix(es):\n\nOpenLDAP 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.(CVE-2026-22185)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"lmdb","purl":"pkg:rpm/openEuler/lmdb&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.31-3.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["lmdb-0.9.31-3.oe2403sp1.aarch64.rpm","lmdb-debuginfo-0.9.31-3.oe2403sp1.aarch64.rpm","lmdb-debugsource-0.9.31-3.oe2403sp1.aarch64.rpm","lmdb-devel-0.9.31-3.oe2403sp1.aarch64.rpm"],"noarch":["lmdb-help-0.9.31-3.oe2403sp1.noarch.rpm"],"src":["lmdb-0.9.31-3.oe2403sp1.src.rpm"],"x86_64":["lmdb-0.9.31-3.oe2403sp1.x86_64.rpm","lmdb-debuginfo-0.9.31-3.oe2403sp1.x86_64.rpm","lmdb-debugsource-0.9.31-3.oe2403sp1.x86_64.rpm","lmdb-devel-0.9.31-3.oe2403sp1.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"lmdb","purl":"pkg:rpm/openEuler/lmdb&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.31-3.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["lmdb-0.9.31-3.oe2403sp3.aarch64.rpm","lmdb-debuginfo-0.9.31-3.oe2403sp3.aarch64.rpm","lmdb-debugsource-0.9.31-3.oe2403sp3.aarch64.rpm","lmdb-devel-0.9.31-3.oe2403sp3.aarch64.rpm"],"noarch":["lmdb-help-0.9.31-3.oe2403sp3.noarch.rpm"],"src":["lmdb-0.9.31-3.oe2403sp3.src.rpm"],"x86_64":["lmdb-0.9.31-3.oe2403sp3.x86_64.rpm","lmdb-debuginfo-0.9.31-3.oe2403sp3.x86_64.rpm","lmdb-debugsource-0.9.31-3.oe2403sp3.x86_64.rpm","lmdb-devel-0.9.31-3.oe2403sp3.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP4","name":"lmdb","purl":"pkg:rpm/openEuler/lmdb&distro=openEuler-24.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.31-3.oe2403sp4"}]}],"ecosystem_specific":{"aarch64":["lmdb-0.9.31-3.oe2403sp4.aarch64.rpm","lmdb-debuginfo-0.9.31-3.oe2403sp4.aarch64.rpm","lmdb-debugsource-0.9.31-3.oe2403sp4.aarch64.rpm","lmdb-devel-0.9.31-3.oe2403sp4.aarch64.rpm"],"noarch":["lmdb-help-0.9.31-3.oe2403sp4.noarch.rpm"],"src":["lmdb-0.9.31-3.oe2403sp4.src.rpm"],"x86_64":["lmdb-0.9.31-3.oe2403sp4.x86_64.rpm","lmdb-debuginfo-0.9.31-3.oe2403sp4.x86_64.rpm","lmdb-debugsource-0.9.31-3.oe2403sp4.x86_64.rpm","lmdb-devel-0.9.31-3.oe2403sp4.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"lmdb","purl":"pkg:rpm/openEuler/lmdb&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.24-5.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["lmdb-0.9.24-5.oe2003sp4.aarch64.rpm","lmdb-debuginfo-0.9.24-5.oe2003sp4.aarch64.rpm","lmdb-debugsource-0.9.24-5.oe2003sp4.aarch64.rpm","lmdb-devel-0.9.24-5.oe2003sp4.aarch64.rpm"],"noarch":["lmdb-help-0.9.24-5.oe2003sp4.noarch.rpm"],"src":["lmdb-0.9.24-5.oe2003sp4.src.rpm"],"x86_64":["lmdb-0.9.24-5.oe2003sp4.x86_64.rpm","lmdb-debuginfo-0.9.24-5.oe2003sp4.x86_64.rpm","lmdb-debugsource-0.9.24-5.oe2003sp4.x86_64.rpm","lmdb-devel-0.9.24-5.oe2003sp4.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"lmdb","purl":"pkg:rpm/openEuler/lmdb&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.30-3.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["lmdb-0.9.30-3.oe2203sp4.aarch64.rpm","lmdb-debuginfo-0.9.30-3.oe2203sp4.aarch64.rpm","lmdb-debugsource-0.9.30-3.oe2203sp4.aarch64.rpm","lmdb-devel-0.9.30-3.oe2203sp4.aarch64.rpm"],"noarch":["lmdb-help-0.9.30-3.oe2203sp4.noarch.rpm"],"src":["lmdb-0.9.30-3.oe2203sp4.src.rpm"],"x86_64":["lmdb-0.9.30-3.oe2203sp4.x86_64.rpm","lmdb-debuginfo-0.9.30-3.oe2203sp4.x86_64.rpm","lmdb-debugsource-0.9.30-3.oe2203sp4.x86_64.rpm","lmdb-devel-0.9.30-3.oe2203sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3283"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22185"}],"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"}],"database_specific":{"severity":"Medium"}}
