Due to the complexity of the Linux boot process, the number of active releases from different distributions with compatibility challenges, and the support and serviceability timelines of in-market products, a limited exception to the NX signing requirements has been granted. 


This limited exception is granted for shims serving in-market products.  This exception will be reviewed regularly, and once component versions are identified that meet the compatibility requirements, new shim signing requests for products targeting the identified components will no longer be exempt. Additionally, when shim functionality is developed to provide compatibility for older, non-compliant boot components, new shim signings will no longer be exempt.
