A physically proximate attacker could use this issue to inject packets. (CVE-2020-26145) It was discovered that a race condition existed in the Atheros Ath9k WiFi driver in the Linux kernel. An attacker could possibly use this to expose sensitive information (WiFi network traffic). (CVE-2020-3702) It was discovered a race condition existed in the Unix domain socket implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-0920) It was discovered that the IPv6 implementation in the Linux kernel contained a use-after-freevulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-0935) Zygo Blaxell discovered that the btrfs file system implementation in the Linux kernel contained a race condition during certain cloning operations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2021-28964) Dan Carpenter discovered that the block device manager (dm) implementation in the Linux kernel contained a buffer overflow in the ioctl for listing devices. A privileged local attacker could use this to cause a denial of service (system crash).

A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-4083) Luo Likang discovered that the FireDTV Firewire driver in the Linux kernel did not properly perform bounds checking in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-42739) Brendan Dolan-Gavitt discovered that the Marvell WiFi-Ex USB device driver in the Linux kernel did not properly handle some error conditions. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2021-43976) Amit Klein discovered that theIPv4 implementation in the Linux kernel could disclose internal state in some situations. An attacker could possibly use this to expose sensitive information. (CVE-2021-45486) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 ESM: linux-image-4.4.0-1104-kvm 4.4.0-1104.113 linux-image-4.4.0-1139-aws 4.4.0-1139.153 linux-image-4.4.0-223-generic 4.4.0-223.256 linux-image-4.4.0-223-lowlatency 4.4.0-223.256 linux-image-aws 4.4.0.1139.144 linux-image-generic 4.4.0.223.230 linux-image-kvm 4.4.0.1104.102 linux-image-lowlatency 4.4.0.223.230 linux-image-virtual 4.4.0.223.230 Ubuntu 14.04 ESM: linux-image-4.4.0-1103-aws 4.4.0-1103.108 linux-image-4.4.0-223-generic 4.4.0-223.256~14.04.1 linux-image-4.4.0-223-lowlatency 4.4.0-223.256~14.04.1 linux-image-aws 4.4.0.1103.101 linux-image-generic-lts-xenial 4.4.0.223.194 linux-image-lowlatency-lts-xenial 4.4.0.223.194 linux-image-virtual-lts-xenial 4.4.0.223.194 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

security advisorydebianprivilege escalationDebian 8 Jessie DLA-1573-1 Critical: Broadcom BCM43xx Wifi Threats
Several vulnerabilities have been discovered in the firmware for Broadcom BCM43xx wifi chips that may lead to a privilege escalation or loss of confidentiality. . Package : firmware-nonfree Version : 20161130-4~deb8u1 CVE ID : CVE-2016-0801 CVE-2017-0561 CVE-2017-9417 CVE-2017-13077 CVE-2017-13078 CVE-2017-13079 CVE-2017-13080 CVE-2017-13081 Debian Bug : 620066 724970 769633 774914 790061 793544 793874 795303 800090 800440 800820 801514 802970 803920 808792 816350 823402 823637 826996 832925 833355 833876 838038 838476 838858 841092 842762 854695 854907 856853 862458 869639 907320 Several vulnerabilities have been discovered in the firmware for Broadcom BCM43xx wifi chips that may lead to a privilege escalation or loss of confidentiality. CVE-2016-0801 Broadgate Team discovered flaws in packet processing in the Broadcom wifi firmware and proprietary drivers that could lead to remote code execution. However, this vulnerability is not believed to affect the drivers used in Debian. CVE-2017-0561 Gal Beniamini of Project Zero discovered a flaw in the TDLS implementation in Broadcom wifi firmware. This could be exploited by an attacker on the same WPA2 network to execute code on the wifi microcontroller. CVE-2017-9417 / #869639 Nitay Artenstein of Exodus Intelligence discovered a flaw in the WMM implementation in Broadcom wifi firmware. This could be exploited by a nearby attacker to execute code on the wifi microcontroller. CVE-2017-13077, CVE-2017-13078, CVE-2017-13079, CVE-2017-13080, CVE-2017-13081 Mathy Vanhoef of the imec-DistriNet research group of KU Leuven discovered multiple vulnerabilities in the WPA protocol used for authentication in wireless networks, dubbed "KRACK". An attacker exploiting the vulnerabilities could force the vulnerable system to reuse cryptographic session keys, enabling a range ofcryptographic attacks against the ciphers used in WPA1 and WPA2. These vulnerabilities are only being fixed for certain Broadcom wifi chips, and might still be present in firmware for other wifi hardware. For Debian 8 "Jessie", these problems have been fixed in version 20161130-4~deb8u1. This version also adds new firmware and packages for use with Linux 4.9, and re-adds firmware-{adi,ralink} as transitional packages. We recommend that you upgrade your firmware-nonfree packages. Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS -- Ben Hutchings - Debian developer, member of kernel, installer and LTS teams . Essential security patches have been released targeting various vulnerabilities in Broadcom BCM43xx Wi-Fi chipsets specifically for Debian operating system users..
