Authenticated system crash via null pointer dereference
Published Feb 13, 2024 · Updated Aug 10, 2026
NULL pointer dereference in Microsoft Windows LDAP allows remote authenticated users to crash the affected system via network requests. The LDAP component dereferences a null pointer while processing attacker-controlled input, although Microsoft has not disclosed the responsible function or request field. Exploitation requires low privileges and no user interaction, and the reported consequence is loss of availability rather than data access or modification.
