Subject: [PATCH 0/2] drm/radeon: Fix off-by-one power_state index heap overwrite
Date: Sun, 2 May 2021 22:06:06 -0700 [thread overview]
Message-ID: <20210503050608.2158996-1-keescook@chromium.org> (raw)
Hi,
This is an attempt at fixing a bug[1] uncovered by the relocation of
the slab freelist pointer offset, as well as some related clean-ups.
I don't have hardware to do runtime testing, but it builds. ;)
