CVE-2026-23156

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

efivarfs: fix error propagation in efivar_entry_get()

efivar_entry_get() always returns success even if the underlying
__efivar_entry_get() fails, masking errors.

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

Fix it by returning the error from __efivar_entry_get().
