NVD description
In ldapd in OpenBSD 7.8 before errata 057 and 7.9 before errata 021, delegated BSD authentication results are correlated only by the LDAP child process client file descriptor and LDAP message ID. After a connection closes, a later connection that reuses the same file descriptor and message ID can receive the earlier authentication result. A remote attacker who can reach ldapd can complete a Bind as another identity. A missing connection can also cause a NULL pointer dereference. (ldapd is not enabled by default.)

I wrote a little writeup to my #OpenBSD finding from last month https://uberblo.gs/2026/09/ldapd-openbsd-cve-2026-103547-fd-reuse-auth/ Also found something really nice that you'll be hearing about soon enough, also #OpenBSD (and some #NetBSD too) https://t.co/reyjQQmZjl
