Christey" <coley@...us.mitre.org> Subject: CVE request: kernel: inotify local DoS According to the upstream commit 3632dee2, if userspace supplies an invalid pointer to a read() of an inotify instance, the inotify device's event list mutex is unlocked twice. This causes an unbalance which effectively leaves the data structure unprotected, and we can trigger oopses by accessing the inotify instance from different tasks concurrently. http://patchwork.kernel.org/patch/4857/ https://bugzilla.redhat.com/show_bug.cgi?id=488935 Thanks, Eugene -- Eugene Teo / Red Hat Security Response Team
