Summary
efivarfs: fix error propagation in efivar_entry_get()
Details

In the Linux kernel, the following vulnerability has been resolved:

efivarfs: fix error propagation in efivarentryget()

efivarentryget() always returns success even if the underlying __efivarentryget() fails, masking errors.

This may result in uninitialized heap memory being copied to userspace in the efivarfsfileread() path.

Fix it by returning the error from __efivarentryget().
