Two issues here, the BUG_ON condition and the OOM dodging issue. Roland proposed the solution to the BUG_ON issue with http://lkml.org/lkml/2010/8/30/463 as opposed to Kee's http://www.openwall.com/lists/oss-security/2010/08/27/1. And Motohiro-san proposed http://lkml.org/lkml/2010/8/29/206 for the OOM dodging issue, but no feedback yet. re: reproducer, Alexander noted http://lkml.org/lkml/2010/8/30/378. So I see two possible two CVE assignments. Introduced by upstream commit b6a2fea39318e43fee84fa7b0b90d68bed92d2ba. For my reference, bug 443659 (rhel-5). The top-level bug for the BUG_ON issue is bug 645222. This bug will be used to address the OOM dodging issue.
