Details

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.
