Updated: Feb 21, 2026

Technical Meaning

The ERROR_NO_SECURITY_ON_OBJECT error, with the numeric code 1350 and hexadecimal representation 0x546, signifies that a security-related operation was attempted on an object that does not have any associated security information. This typically means that the object lacks necessary permissions or access control lists (ACLs) required for performing certain operations.

Error Details

This error is returned when a function or API call requires security context to be established, but the target object does not possess such context. Common scenarios where this might occur include attempts to modify ACLs, set ownership, or perform other security-sensitive actions on an object that has no defined security descriptor.

Usage Context

The error is relevant in contexts where security operations are expected, such as modifying file permissions, changing directory access controls, or setting ownership. It indicates that the operation cannot proceed without a valid security context for the target object.

Developer Interpretation

When encountering this error, developers should ensure that the objects being manipulated have appropriate security descriptors and that the necessary privileges are available to perform the required operations. This might involve verifying the existence of ACLs or ensuring that the process has sufficient permissions to modify the object's security settings.
