[Ksplice-Fedora-29-updates] New Ksplice updates for Fedora 29 (FEDORA-2019-20ac2c6b4d)

[Oracle Ksplice]

Synopsis: FEDORA-2019-20ac2c6b4d can now be patched using Ksplice

Systems running Fedora 29 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2019-20ac2c6b4d.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Fedora 29
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

* Memory leak when sending messages over sctp socket.

A missing free of resources when sending messages over sctp socket could
lead to a memory leak. A local attacker could use this flaw to exhaust
kernel memory and cause a denial-of-service.


* NULL pointer dereference when using Match-all network packet classifier.

A missing check when receiving a packet while Match-all packet
classifier is not completely initialized could cause a NULL pointer
dereference. A remote attacker could use this flaw to cause a
denial-of-service.


* Use-after-free when server rejects RPCSEC_GSS credential in Sunrpc network driver.

A logic error when server rejects RPCSEC_GSS credential in Sunrpc network
driver could lead to a use-after-free on client side. A local attacker
could use this flaw to cause a denial-of-service.


* Data corruption when using COPY_FILE_RANGE opcode of fuse filesystem.

A missing flush of dirty pages when using COPY_FILE_RANGE opcode of fuse
filesystem could lead to on-disk data corruption.


* Use-after-free when accessing LDT entry.

A locking error while accessing LDT entry could lead to a
use-after-free. A local attacker could use this flaw to cause a
denial-of-service.


* Integer overflow in GenWQE PCIe Accelerator driver.

A missing check on user input in one of the GenWQE PCIe Accelerator
driver ioctl could lead to an integer overflow. A local attacker could
use this flaw to cause a denial-of-service or escalate privileges.


* Memory leak when releasing packet with PACKET_FANOUT_ROLLOVER mode enabled.

A missing free of resource when releasing packet with
PACKET_FANOUT_ROLLOVER mode enabled 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 allocating a file fails on fuse filesystem.

A wrong error path when allocating a file fails on fuse filesystem could
lead to a reference leak. A local attacker could use this flaw to
exhaust kernel memory and cause a denial-of-service.


* Information leak when using Intel GVT-g graphics virtualization host driver.

A missing initialization of on stack data when using Intel GVT-g
graphics virtualization host driver could lead to a memory leak. A local
attacker could use this flaw to leak information about running kernel
and facilitate an attack.


* Invalid memory accesses in HabanaLabs AI accelerators driver debugfs.

Logic errors in HabanaLabs AI accelerators driver debugfs could lead to
invalid memory accesses. A local attacker could use this flaw to cause a
denial-of-service.


* Use-after-free when unregistering persistent storage driver.

A logic error when unregistering persistent storage driver could lead to
a use-after-free. A local attacker could use this flaw to cause a
denial-of-service.
