DESCRIPTION

* Crash in InfiniBand Mellanox ConnectX HCA driver Shared Receive Queue free.

The InfiniBand Mellanox ConnectX HCA driver used the incorrect free type
when releasing a shared receive queue causing a crash or memory leak.


* CVE-2016-3134: Privilege escalation in the Netfilter driver.

Incomplete input validation when processing Netfilter xtables entries could
lead to out of bounds memory read and write.  An unprivileged user inside a
container could use this flaw to cause a denial-of-service or elevate
privileges


* Crash due to watchdog sample interval mismatch.

The watchdog_thresh sysctl did not fully update the logic for the
watchdog triggering and in some circumstances the watchdog could assert
incorrectly, causing a panic.


* Hang in OCFS2 due to incorrect quota check.

Incorrect initialisation of quota information can cause a hang
on OCFS2 filesystems.


* Return non-zero block length for really small files on ocfs2.

Tools like tar and rsync assume a file has no data if the block
length is 0 and will skip reading them.


* CVE-2016-5829: Memory corruption in unknown USB HID devices.

The USB HID driver does not validate USB data when an unknown HID device
is encountered which can allow a malicious USB device to trigger kernel
memory corruption and gain code execution.


* Use-after-free in ocfs2 driver during file write.

Incorrect reference counting in the ocfs2 driver if an error occurs
during file write can lead to a kernel crash.
