### Description
In the Linux kernel, the following vulnerability has been resolved:keys: Fix overwrite of key expiration on instantiationThe expiry time of a key is unconditionally overwritten duringinstantiation, defaulting to turn it permanent. This causes a problemfor DNS resolution as the expiration set by user-space is overwritten toTIME64_MAX, disabling further DNS updates. Fix this by restoring thecondition that key_set_expiry is only called when the pre-parser sets aspecific expiry.
