The __request_module function in kernel/kmod.c in the Linux kernel before 3.4 does not set a certain killable attribute, which allows local users to cause a denial of service (memory consumption) via a crafted application.

Memory leak in drivers/net/xen-netback/netback.c in the Xen netback functionality in the Linux kernel before 3.7.8 allows guest OS users to cause a denial of service (memory consumption) by triggering certain error conditions.

The pciback_enable_msi function in the PCI backend driver (drivers/xen/pciback/conf_space_capability_msi.c) in Xen for the Linux kernel 2.6.18 and 3.8 allows guest OS users with PCI device access to cause a denial of service via a large number of kernel log messages. NOTE: some of these details are obtained from third party information.

The main function in tools/hv/hv_kvp_daemon.c in hypervkvpd, as distributed in the Linux kernel before 3.8-rc1, allows local users to cause a denial of service (daemon exit) via a crafted application that sends a Netlink message. NOTE: this vulnerability exists because of an incorrect fix for CVE-2012-2669.

The online_pages function in mm/memory_hotplug.c in the Linux kernel before 3.6 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact in opportunistic circumstances by using memory that was hot-added by an administrator.

The override_release function in kernel/sys.c in the Linux kernel before 3.4.16 allows local users to obtain sensitive information from kernel stack memory via a uname system call in conjunction with a UNAME26 personality.

Race condition in fs/ext4/extents.c in the Linux kernel before 3.4.16 allows local users to obtain sensitive information from a deleted file by reading an extent that was not properly marked as uninitialized.

The (1) do_siocgstamp and (2) do_siocgstampns functions in net/socket.c in the Linux kernel before 3.5.4 use an incorrect argument order, which allows local users to obtain sensitive information from kernel memory or cause a denial of service (system crash) via a crafted ioctl call.

Multiple race conditions in the madvise_remove function in mm/madvise.c in the Linux kernel before 3.4.5 allow local users to cause a denial of service (use-after-free and system crash) via vectors involving a (1) munmap or (2) close system call.

The epoll_ctl system call in fs/eventpoll.c in the Linux kernel before 3.2.24 does not properly handle ELOOP errors in EPOLL_CTL_ADD operations, which allows local users to cause a denial of service (file-descriptor consumption and system crash) via a crafted application that attempts to create a circular epoll dependency. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-1083.
