The firmware-nonfree package has been updated to include addtional firmware
that may be requested by some drivers in Linux 5.10, availble for Debian LTS as
backported kernel.
Some of the updated firmware files adresses security vulnerabilities, which may
allow Escalation of Privileges, Denial of Services and Information Disclosures.
CVE-2020-24586 (INTEL-SA-00473)
The 802.11 standard that underpins Wi-Fi Protected Access (WPA,
WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require
that received fragments be cleared from memory after (re)connecting
to a network. Under the right circumstances, when another device
sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can
be abused to inject arbitrary network packets and/or exfiltrate user
data.
CVE-2020-24587 (INTEL-SA-00473)
The 802.11 standard that underpins Wi-Fi Protected Access (WPA,
WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require
that all fragments of a frame are encrypted under the same key. An
adversary can abuse this to decrypt selected fragments when another
device sends fragmented frames and the WEP, CCMP, or GCMP encryption
key is periodically renewed.
CVE-2020-24588 (INTEL-SA-00473)
The 802.11 standard that underpins Wi-Fi Protected Access (WPA,
WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require
that the A-MSDU flag in the plaintext QoS header field is
authenticated. Against devices that support receiving non-SSP A-MSDU
frames (which is mandatory as part of 802.11n), an adversary can
abuse this to inject arbitrary network packets.
CVE-2021-23168 (INTEL-SA-00621)
Out of bounds read for some Intel(R) PROSet/Wireless WiFi and
Killer(TM) WiFi products may allow an unauthenticated user to
potentially enable denial of service via adjacent access.
CVE-2021-23223 (INTEL-SA-00621)
Improper initialization for some Intel(R) PROSet/Wireless WiFi and
Killer(TM) WiFi products may allow a privileged user to potentially
enable escalation of privilege via local access.
CVE-2021-37409 (INTEL-SA-00621)
Improper access control for some Intel(R) PROSet/Wireless WiFi and
Killer(TM) WiFi products may allow a privileged user to potentially
enable escalation of privilege via local access.
CVE-2021-44545 (INTEL-SA-00621)
Improper input validation for some Intel(R) PROSet/Wireless WiFi and
Killer(TM) WiFi products may allow an unauthenticated user to
potentially enable denial of service via adjacent access.
CVE-2022-21181 (INTEL-SA-00621)
Improper input validation for some Intel(R) PROSet/Wireless WiFi and
Killer(TM) WiFi products may allow a privileged user to potentially
enable escalation of privilege via local access.
The following advisories are also fixed by this upload, but needs an
updated Linux kernel to load the updated firmware:
CVE-2020-12362 (INTEL-SA-00438)
Integer overflow in the firmware for some Intel(R) Graphics Drivers
for Windows * before version 26.20.100.7212 and before Linux kernel
version 5.5 may allow a privileged user to potentially enable an
escalation of privilege via local access.
CVE-2020-12363 (INTEL-SA-00438)
Improper input validation in some Intel(R) Graphics Drivers for
Windows* before version 26.20.100.7212 and before Linux kernel
version 5.5 may allow a privileged user to potentially enable a
denial of service via local access.
CVE-2020-12364 (INTEL-SA-00438)
Null pointer reference in some Intel(R) Graphics Drivers for
Windows* before version 26.20.100.7212 and before version Linux
kernel version 5.5 may allow a privileged user to potentially enable
a denial of service via local access.
For Debian 10 buster, these problems have been fixed in version
20190114+really20220913-0+deb10u1.
We recommend that you upgrade your firmware-nonfree packages.
