ERROR_DS_SEC_DESC_TOO_SHORT - 8353 (0x20A1)
The security descriptor is too short.
Updated: Feb 21, 2026
Technical Meaning
The error code ERROR_DS_SEC_DESC_TOO_SHORT indicates that a security descriptor provided to a Windows API function is insufficient in length. A security descriptor is a structure used by the Windows operating system to define access control for objects such as files, directories, and registry keys.
Error Details
A security descriptor consists of several components including an owner SID (Security Identifier), a group SID, and DACLs (Discretionary Access Control Lists). If any part of this structure is too short or improperly formatted, the API function will return this error code. The exact length required can vary based on the specific type of object being secured.
Usage Context
This error typically occurs when a security descriptor is passed to functions such as SetSecurityInfo or GetNamedSecurityInfo. These functions are used for managing access control lists and other security-related information in Windows applications. The error suggests that the provided security descriptor does not meet the minimum length requirements necessary for proper functioning.
Developer Interpretation
When encountering this error, developers should ensure that the security descriptors they provide to API functions are correctly formatted and of sufficient length. This includes verifying the size and structure of the descriptor components such as SIDs and DACLs. Developers should also consult the documentation specific to the function being used for detailed requirements regarding the format and minimum lengths of security descriptors.
