Description Petr Matousek 2013-06-18 11:57:12 UTC
A flaw was found in the way do_filp_open() function in the Linux kernel handled cleanup in case write access to a mount was denied. A local unprivileged user with acces to a read-only mount could use this flaw to crash the system.

This issue affected Red Hat Enterprise Linux 6 only. Upstream is not affected.


This issue was discovered by Mateusz Guzik of Red Hat.
