[Ksplice-Fedora-28-updates] New Ksplice updates for Fedora 28 (FEDORA-2019-3516fa2764)

[Oracle Ksplice]

Synopsis: FEDORA-2019-3516fa2764 can now be patched using Ksplice

Systems running Fedora 28 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2019-3516fa2764.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Fedora 28
install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* Denial-of-service when adding a multicast forwarding entry in IPV6.

A logic error when adding a multicast forwarding entry in IPV6 could
lead to a deadlock. A local attacker could use this flaw to cause a
denial-of-service.


* Memory leak when registering a kobject associated to a net device.

A missing free of resources when registering a kobject for a net device
fails could lead to a memory leak. A local attacker could use this flaw
to exhaust kernel memory and cause a denial-of-service.


* Memory leak when unregistering an Ethernet team driver.

A missing free of a BPF filter when unregistering an Ethernet team
driver could lead to a memory leak. A local attacker could use this flaw
to exhaust kernel memory and cause a denial-of-service.


* Out-of-bounds memory accesses when using netlabel subsystem.

Logic errors when using netlabel subsystem could lead to out-of-bounds
memory accesses. A local attacker could use this flaw to cause a
denial-of-service.


* Denial-of-service when network emulator is used.

A logic error when network emulator is used could lead to a kernel
assert. A local attacker could use this flaw to cause a
denial-of-service.


* NULL pointer dereference when registering an NFC device.

A missing check when registering an NFC device could lead to a NULL
pointer dereference. A local attacker could use this flaw to cause a
denial-of-service.


* Memory leak when registering an IPv6-in-IPv4 tunnel.

A missing free of resources when registering an IPv6-in-IPv4 tunnel fails
could lead to a memory leak. A local attacker could use this flaw to
exhaust kernel memory and cause a denial-of-service.


* Use-after-free when releasing a socket.

A logic error when releasing a socket could lead to a use-after-free. A
local attacker could use this flaw to cause a denial-of-service.


* Multiple refcount leaks when using network packet editing and SKB editing.

Logic errors when using network packet editing and SKB editing could
lead to memory leaks. A local attacker could use this flaw to exhaust
kernel memory and cause a denial-of-service.


* NULL pointer dereference when registering IP tunnel metadata.

A logic error when registering IP tunnel metadata could lead to a NULL
pointer dereference. A local attacker could use this flaw to cause a
denial-of-service.


* Deadlock when using polling with POSIX asynchronous I/O driver.

A race condition when using polling with POSIX asynchronous I/O driver
could lead to a deadlock. A local attacker could use this flaw to cause
a denial-of-service.
