updates to mitigate these potential vulnerabilities.


VULNERABILITY DETAILS: 

CVEID:  CVE-2024-21801

Description: Insufficient control flow management in some Intel® TDX module
software before version 1.5.05.46.698 may allow a privileged user to potentially
enable denial of service via local access.

CVSS Base Score 3.1: 7.1 High

CVSS Vector 3.1:  CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H

CVSS Base Score 4.0: 8.3 High

CVSS Vector 4.0:
 CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:N/SC:H/SI:N/SA:N


AFFECTED PRODUCTS:

Intel® TDX module software versions before version 1.5.05.46.698.


RECOMMENDATION:

Intel recommends that users of the Intel® TDX module update to the latest
version provided by the system manufacturer that addresses these issues.


ACKNOWLEDGEMENTS:

This issue was found internally by Intel.

Intel, and nearly the entire technology industry, follows a disclosure practice
called Coordinated Disclosure, under which a cybersecurity vulnerability is
generally publicly disclosed only after mitigations are available.

STRICTLY NECESSARY COOKIES

Always Active

These technologies are necessary for the Intel experience to function and cannot
be switched off in our systems. The technology is usually only set in response
to actions made by the device owner which amount to a request for services, such
as setting privacy preferences, logging in, filling in forms, maintaining secure
login areas, maintaining state across pages (remembering items in a shopping
basket), and server load balancing. The device owner can set their preference to
block or alert Intel about these technologies, but some parts of the Intel
experience will not work. These technologies do not store any personally
identifiable information.

Cookies Details‎

ANALYTICS

Analytics Active


These technologies allow Intel to count device visits and traffic sources, so
Intel can measure and improve the performance of our experiences. The technology
helps Intel to know which experiences are the most and least popular and see how
device owners interact with the experience. All information these technologies
collect is aggregated. If the device owner does not allow these technologies,
then Intel will not know when the device owner visited or how the device owner
interacted with our experiences.

Cookies Details‎

FUNCTIONAL

Functional Active


These technologies enable the Intel experience to provide enhanced functionality
and personalization. The technology may be set by Intel or by third-party
providers whose services Intel have added to our experiences. If the device
owner does not allow these technologies, then some or all of these services may
not function properly for the device owner.

Cookies Details‎

AD TARGETING

Ad Targeting Active


These technologies may be set through our Intel experience or by our advertising
partners. The technology may be used to build a profile of the device owner’s
interests and show the device owner relevant advertisements on other
experiences. The technology does not store directly personal information on the
device, but the technology is based on uniquely identifying the device. If the
device owner does not allow these technologies, then the device owner will
experience less targeted advertising.
