INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running RHCK 9 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

* CVE-2021-47383: Privilege escalation in Virtual Terminal driver.

A logic error when resizing screen in the Virtual Terminal driver could
lead to an out-of-bounds memory access. A local attacker could use this
flaw to gain root privileges.


* CVE-2024-26640: Denial-of-service in TCP/IP networking.

A logic error in TCP/IP networking could lead to a kernel assert. A
local attacker could use this flaw to cause a denial-of-service.


* CVE-2024-26923: Privilege escalation in Unix domain sockets.

A race condition when using Unix domain sockets could lead to the
garbage collector racing with the connect() syscall. A local attacker
could use this flaw to escalate privileges.


* CVE-2024-36244: Denial-of-service in Time Aware Priority (taprio) Scheduler driver.

A logic error when using the Time Aware Priority (taprio) Scheduler
driver could lead to a deadlock. A local attacker could use this flaw to
cause a denial-of-service.


* CVE-2024-39472: Denial-of-service in XFS filesystem driver.

A logic error when using the XFS filesystem driver could lead to an out-
of-bounds memory access. A local attacker could use this flaw to cause a
denial-of-service.


* CVE-2024-39504: Denial-of-service in Network packet filtering framework.

A missing check when using the Network packet filtering framework
(Netfilter) driver could lead to a NULL pointer dereference. A local
attacker could use this flaw to cause a denial-of-service.


* CVE-2024-40904: Denial-of-service in core USB subsystem.

A logic error when using the core USB subsystem could lead to soft
lockup due to excessive logging. A local attacker could use this flaw to
cause a denial-of-service.


* CVE-2024-40995: Denial-of-service in networking traffic control actions stack.

A logic error when using the networking traffic control actions stack
could lead to a deadlock. A local attacker could use this flaw to cause
a denial-of-service.


* CVE-2024-41013: Privilege escalation in XFS filesystem driver.

A missing check when using the XFS filesystem driver could lead to an
out-of-bounds memory access. A local attacker could use this flaw and a
crafted XFS image to gain root privileges.


* CVE-2024-41014: Privilege escalation in XFS filesystem driver.

A missing check when manipulating images in the XFS filesystem driver
could lead to an out-of-bounds memory access. A local attacker could use
this flaw to gain root privileges.


* CVE-2024-43854: Information leak in Block layer data integrity driver.

A missing variable initialization when using the Block layer data
integrity driver could lead to use of uninitialized memory. A local
attacker could use this flaw to extract sensitive information.


* CVE-2024-45018: Information leak in Network packet filtering framework.

A missing variable initialization in the Network packet
filtering framework (Netfilter) driver could lead to use of
uninitialized memory. A local attacker could use this flaw to
extract sensitive information.


* CVE-2024-50017: Denial-of-service in memory management subsystem.

A logic error when mapping memory pages can cause inclusion of
regions that will cause hardware to halt the system if accessed.
A local attacker could use this flaw as a step to cause a
denial-of-service.


* Note: Oracle will not provide a zero-downtime update for CVE-2024-2201.

The fix for this CVE on systems running EL9 is a microcode update for
affected CPUs. Customers will need to upgrade the microcode on affected
CPUs in order to mitigate this vulnerability.
