From 02a077c52ef7631275a79862ffd9f3dbe9d38bc2 Mon Sep 17 00:00:00 2001 From: Rajiv Andrade Date: Mon, 14 Jun 2010 13:58:22 -0300 Subject: TPM: ReadPubEK output struct fix This patch adds a missing element of the ReadPubEK command output, that prevents future overflow of this buffer when copying the TPM output result into it. Prevents a kernel panic in case the user tries to read the pubek from sysfs.
