Integer overflow in the fb_mmap function in drivers/video/fbmem.c in
the Linux kernel before 3.8.9, as used in a certain Motorola build
of Android 4.1.2 and other products, allows local users to create
a read-write memory mapping for the entirety of kernel memory,
and consequently gain privileges, via crafted /dev/graphics/fb0
mmap2 system calls, as demonstrated by the Motochopper pwn
program. (CVE-2013-2596)
arch/x86/kernel/cpu/perf_event_intel.c in the Linux kernel before
3.8.9, when the Performance Events Subsystem is enabled, specifies
an incorrect bitmask, which allows local users to cause a denial of
service (general protection fault and system crash) by attempting to
set a reserved bit. (CVE-2013-2146)
The perf_swevent_init function in kernel/events/core.c in the Linux
kernel before 3.8.9 uses an incorrect integer data type, which allows
local users to gain privileges via a crafted perf_event_open system
call. (CVE-2013-2094)
The ioapic_read_indirect function in virt/kvm/ioapic.c in the Linux
kernel through 3.8.4 does not properly handle a certain combination
of invalid IOAPIC_REG_SELECT and IOAPIC_REG_WINDOW operations, which
allows guest OS users to obtain sensitive information from host OS
memory or cause a denial of service (host OS OOPS) via a crafted
application. (CVE-2013-1798)
Use-after-free vulnerability in arch/x86/kvm/x86.c in the Linux kernel
through 3.8.4 allows guest OS users to cause a denial of service (host
OS memory corruption) or possibly have unspecified other impact via a
crafted application that triggers use of a guest physical address (GPA)
in (1) movable or (2) removable memory during an MSR_KVM_SYSTEM_TIME
kvm_set_msr_common operation. (CVE-2013-1797)
The kvm_set_msr_common function in arch/x86/kvm/x86.c in the Linux
kernel through 3.8.4 does not ensure a required time_page alignment
during an MSR_KVM_SYSTEM_TIME operation, which allows guest OS users
to cause a denial of service (buffer overflow and host OS memory
corruption) or possibly have unspecified other impact via a crafted
application. (CVE-2013-1796)
The do_tkill function in kernel/signal.c in the Linux kernel before
3.8.9 does not initialize a certain data structure, which allows
local users to obtain sensitive information from kernel memory via
a crafted application that makes a (1) tkill or (2) tgkill system
call. (CVE-2013-2141)
Heap-based buffer overflow in the tg3_read_vpd function in
drivers/net/ethernet/broadcom/tg3.c in the Linux kernel before 3.8.6
allows physically proximate attackers to cause a denial of service
(system crash) or possibly execute arbitrary code via crafted firmware
that specifies a long string in the Vital Product Data (VPD) data
structure. (CVE-2013-1929)
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. (CVE-2012-5532)
The udf_encode_fh function in fs/udf/namei.c in the Linux kernel
before 3.6 does not initialize a certain structure member, which
allows local users to obtain sensitive information from kernel heap
memory via a crafted application. (CVE-2012-6548)
The isofs_export_encode_fh function in fs/isofs/export.c in the Linux
kernel before 3.6 does not initialize a certain structure member,
which allows local users to obtain sensitive information from kernel
heap memory via a crafted application. (CVE-2012-6549)
net/dcb/dcbnl.c in the Linux kernel before 3.8.4 does not
initialize certain structures, which allows local users to obtain
sensitive information from kernel stack memory via a crafted
application. (CVE-2013-2634)
The rtnl_fill_ifinfo function in net/core/rtnetlink.c in the Linux
kernel before 3.8.4 does not initialize a certain structure member,
which allows local users to obtain sensitive information from kernel
stack memory via a crafted application. (CVE-2013-2635)
fs/ext3/super.c in the Linux kernel before 3.8.4 uses incorrect
arguments to functions in certain circumstances related to printk
input, which allows local users to conduct format-string attacks and
possibly gain privileges via a crafted application. (CVE-2013-1848)
The flush_signal_handlers function in kernel/signal.c in the Linux
kernel before 3.8.4 preserves the value of the sa_restorer field across
an exec operation, which makes it easier for local users to bypass
the ASLR protection mechanism via a crafted application containing
a sigaction system call. (CVE-2013-0914)
Heap-based buffer overflow in the wdm_in_callback function in
drivers/usb/class/cdc-wdm.c in the Linux kernel before 3.8.4 allows
physically proximate attackers to cause a denial of service (system
crash) or possibly execute arbitrary code via a crafted cdc-wdm USB
device. (CVE-2013-1860)
Race condition in the install_user_keyrings function in
security/keys/process_keys.c in the Linux kernel before 3.8.3 allows
local users to cause a denial of service (NULL pointer dereference
and system crash) via crafted keyctl system calls that trigger keyring
operations in simultaneous threads. (CVE-2013-1792)
The report API in the crypto user configuration API in the Linux
kernel through 3.8.2 uses an incorrect C library function for
copying strings, which allows local users to obtain sensitive
information from kernel stack memory by leveraging the CAP_NET_ADMIN
capability. (CVE-2013-2546)
The crypto_report_one function in crypto/crypto_user.c in the report
API in the crypto user configuration API in the Linux kernel through

local users to obtain sensitive information from kernel heap memory
by leveraging the CAP_NET_ADMIN capability. (CVE-2013-2547)
The crypto_report_one function in crypto/crypto_user.c in the report
API in the crypto user configuration API in the Linux kernel through
3.8.2 uses an incorrect length value during a copy operation, which
allows local users to obtain sensitive information from kernel memory
by leveraging the CAP_NET_ADMIN capability. (CVE-2013-2548)
The translate_desc function in drivers/vhost/vhost.c in the Linux
kernel before 3.7 does not properly handle cross-region descriptors,
which allows guest OS users to obtain host OS privileges by leveraging
KVM guest OS privileges. (CVE-2013-0311)
Array index error in the __sock_diag_rcv_msg function in
net/core/sock_diag.c in the Linux kernel before 3.7.10 allows local
users to gain privileges via a large family value in a Netlink
message. (CVE-2013-1763)
The __skb_recv_datagram function in net/core/datagram.c in the
Linux kernel before 3.8 does not properly handle the MSG_PEEK
flag with zero-length data, which allows local users to cause a
denial of service (infinite loop and system hang) via a crafted
application. (CVE-2013-0290)
Use-after-free vulnerability in the shmem_remount_fs function in
mm/shmem.c in the Linux kernel before 3.7.10 allows local users to gain
privileges or cause a denial of service (system crash) by remounting
a tmpfs filesystem without specifying a required mpol (aka mempolicy)
mount option. (CVE-2013-1767)
The xen_iret function in arch/x86/xen/xen-asm_32.S in the Linux
kernel before 3.7.9 on 32-bit Xen paravirt_ops platforms does not
properly handle an invalid value in the DS segment register, which
allows guest OS users to gain guest OS privileges via a crafted
application. (CVE-2013-0228)
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. (CVE-2013-0217)
The Xen netback functionality in the Linux kernel before 3.7.8 allows
guest OS users to cause a denial of service (loop) by triggering ring
pointer corruption. (CVE-2013-0216)
The __tun_chr_ioctl function in drivers/net/tun.c in the Linux kernel
before 3.6 does not initialize a certain structure, which allows
local users to obtain sensitive information from kernel stack memory
via a crafted application. (CVE-2012-6547)
