- CVEs with nessus.description==Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service, information
leak or data loss.
- CVE-2013-4312, CVE-2016-2847
Tetsuo Handa discovered that users can use pipes queued
on local (Unix) sockets to allocate an unfair share of
kernel memory, leading to denial-of-service (resource
exhaustion).
This issue was previously mitigated for the stable suite by limiting
the total number of files queued by each user on local sockets. The
new kernel version in both suites includes that mitigation plus
limits on the total size of pipe buffers allocated for each user.
- CVE-2015-7566
Ralf Spenneberg of OpenSource Security reported that the
visor driver crashes when a specially crafted USB device
without bulk-out endpoint is detected.
- CVE-2015-8767
An SCTP denial-of-service was discovered which can be
triggered by a local attacker during a heartbeat timeout
event after the 4-way handshake.
- CVE-2015-8785
It was discovered that local users permitted to write to
a file on a FUSE filesystem could cause a denial of
service (unkillable loop in the kernel).
- CVE-2015-8812
A flaw was found in the iw_cxgb3 Infiniband driver.
Whenever it could not send a packet because the network
was congested, it would free the packet buffer but later
attempt to send the packet again. This use-after-free
could result in a denial of service (crash or hang),
data loss or privilege escalation.
- CVE-2015-8816
A use-after-free vulnerability was discovered in the USB
hub driver. This may be used by a physically present
user for privilege escalation.
- CVE-2015-8830
Ben Hawkes of Google Project Zero reported that the AIO
interface permitted reading or writing 2 GiB of data or
more in a single chunk, which could lead to an integer
overflow when applied to certain filesystems, socket or
device types. The full security impact has not been
evaluated.
- CVE-2016-0723
A use-after-free vulnerability was discovered in the
TIOCGETD ioctl. A local attacker could use this flaw for
denial-of-service.
- CVE-2016-0774
It was found that the fix for CVE-2015-1805 in kernel
versions older than Linux 3.16 did not correctly handle
the case of a partially failed atomic read. A local,
unprivileged user could use this flaw to crash the
system or leak kernel memory to user space.
- CVE-2016-2069
Andy Lutomirski discovered a race condition in flushing
of the TLB when switching tasks on an x86 system. On an
SMP system this could possibly lead to a crash,
information leak or privilege escalation.
- CVE-2016-2384
Andrey Konovalov found that a crafted USB MIDI device
with an invalid USB descriptor could trigger a
double-free. This may be used by a physically present
user for privilege escalation.
- CVE-2016-2543
Dmitry Vyukov found that the core sound sequencer driver
(snd-seq) lacked a necessary check for a NULL pointer,
allowing a user with access to a sound sequencer device
to cause a denial-of service (crash).
- CVE-2016-2544, CVE-2016-2546, CVE-2016-2547,
CVE-2016-2548
Dmitry Vyukov found various race conditions in the sound
subsystem (ALSA)'s management of timers. A user with
access to sound devices could use these to cause a
denial-of-service (crash or hang) or possibly for
privilege escalation.
- CVE-2016-2545
Dmitry Vyukov found a flaw in list manipulation in the
sound subsystem (ALSA)'s management of timers. A user
with access to sound devices could use this to cause a
denial-of-service (crash or hang) or possibly for
privilege escalation.
- CVE-2016-2549
Dmitry Vyukov found a potential deadlock in the sound
subsystem (ALSA)'s use of high resolution timers. A user
with access to sound devices could use this to cause a
denial-of-service (hang).
- CVE-2016-2550
The original mitigation of CVE-2013-4312, limiting the
total number of files a user could queue on local
sockets, was flawed. A user given a local socket opened
by another user, for example through the systemd socket
activation mechanism, could make use of the other user's
quota, again leading to a denial-of-service (resource
exhaustion). This is fixed by accounting queued files to
the sender rather than the socket opener.
