Christey" <coley@...us.mitre.org> Subject: CVE request: kernel: NULL pointer dereference in sg_build_indirect() Backtrace: http://lkml.org/lkml/2009/9/3/1 Upstream proposed patch: http://lkml.org/lkml/2009/9/3/107 Triggered by firing up "xcdroast" to duplicate a CD. [...] out: for (i = 0; i < k; i++) - __free_pages(schp->pages[k], order); + __free_pages(schp->pages[i], order); When the allocation in sg_build_indirect() fails, an oops can occur because of an obvious typo. This was introduced by upstream commit 10db10d1 in v2.6.28-rc1. Thanks, Eugene
