[PATCH v3 0/2] bootconfig: Fix integer overflow problems

Posted by Masami Hiramatsu (Google) 2 weeks, 1 day ago

Hi,

Here are patches to fix bootconfig size overflow issue. If there is a wrong
bootconfig size is recorded, it can bypass the size check in the tool and the
kernel.

The previous version only fixes tools, but Sashiko found the same issue in
the kernel. So this version add that fix.

Here is the previous version.

Thank you,
