Bug ID: 88882 Summary: hud_context.c: possible NULL-pointer dereference Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: xypron.glpk@gmx.de QA Contact: dri-devel@lists.freedesktop.org

In mesa/src/gallium/auxiliary/hud/hud_context.c we find the following code

case ',': env++; y += height + hud->font.glyph_height * (pane->num_graphs + 2);

if (pane && pane->num_graphs) { LIST_ADDTAIL(&pane->head, &hud->pane_list); pane = NULL; } break;

pane is checked for being NULL. So obviously we expect NULL as possible value. But we use pane->num_graphs before the check. This is possibly a NULL-pointer dereference.

The problem was indicated by cppcheck http://cppcheck.sourceforge.net/
