Error description
Various abends due to storage overlay in CCB when AUTOBIND and when access control authorization exit is used ABEND0C4 RC00000010 at DSN3AMGP.DSN3AUCM+0B06 ABEND0C4 RC00000010 at DSNSLD1 .DSNSVBK +0928 ABEND0C4 RC00000010 at DSNWVAPR.DSNWVAPR+0F18 ABEND0C4 RC00000010 at DSNSLD1 .DSNSCON2+0A7A ABEND04E RC00E20005 at DSN3AUCM.DSNSVBK +0994 ABEND04E RC00E2000E at DSN3AUCM.DSNSFBK +118A and other abends such as RC00E2000D at other csects are possible. DB2 may terminate with RC00F30408. The common symptom is: the thread experiencing the abend is the AUTBND06 service task and the storage being overlaid is in CCB block CCBUSER_STR for x'100' bytes. The access control exit can be the DB2 "Access control authorization exit(DSNX@XAC)" or a vendor product keywords: smcoverlay DB2STGLK/K
Local fix
Rebind the invalidated or old plans before autobind or disable AUTOBIND, if possible

Code has been changed to check for a valid length before copying the authorization ID field.
