(CVE-2021-3543) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 21.04: linux-image-5.11.0-1009-azure 5.11.0-1009.9 linux-image-5.11.0-1010-oracle 5.11.0-1010.10 linux-image-5.11.0-1011-aws 5.11.0-1011.11 linux-image-5.11.0-1011-gcp 5.11.0-1011.12 linux-image-5.11.0-1012-raspi 5.11.0-1012.13 linux-image-5.11.0-1012-raspi-nolpae 5.11.0-1012.13 linux-image-5.11.0-22-generic 5.11.0-22.23 linux-image-5.11.0-22-generic-64k 5.11.0-22.23 linux-image-5.11.0-22-generic-lpae 5.11.0-22.23 linux-image-5.11.0-22-lowlatency 5.11.0-22.23 linux-image-aws 5.11.0.1011.11 linux-image-azure 5.11.0.1009.9 linux-image-gcp 5.11.0.1011.11 linux-image-generic 5.11.0.22.23 linux-image-generic-64k 5.11.0.22.23 linux-image-generic-lpae 5.11.0.22.23 linux-image-gke 5.11.0.1011.11 linux-image-lowlatency 5.11.0.22.23 linux-image-oracle 5.11.0.1010.10 linux-image-raspi 5.11.0.1012.10 linux-image-raspi-nolpae 5.11.0.1012.10 linux-image-virtual 5.11.0.22.23 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.

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. IEEE 802.11 The standard has vulnerabilities regarding cryptographic strength.Information may be obtained. A flaw was found in the Linux kernel's WiFi implementation. An attacker within the wireless range can abuse a logic flaw in the WiFi implementation by reassembling packets from multiple fragments under different keys, treating them as valid. This flaw allows an malicious user to send a fragment under an incorrect key, treating them as a valid fragment under the new key. The highest threat from this vulnerability is to confidentiality. 8) - x86_64 3. Description: The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

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.

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. IEEE 802.11 The standard has vulnerabilities related to lack of certification for critical functions.Information may be tampered with. A flaw was found in the Linux kernels implementation of wifi fragmentation handling. An attacker with the ability to transmit within the wireless transmission range of an access point can abuse a flaw where previous contents of wifi fragments can be unintentionally transmitted to another device. (CVE-2020-24586) A flaw was found in the Linux kernel's WiFi implementation. An attacker within the wireless range can abuse a logic flaw in the WiFi implementation by reassembling packets from multiple fragments under different keys, treating them as valid. This flaw allows an malicious user to send a fragment under an incorrect key, treating them as a valid fragment under the new key. The highest threat from this vulnerability is to confidentiality. (CVE-2020-24587) A flaw was found in the Linux kernels wifi implementation. An attacker within wireless broadcast range can inject custom data into the wireless communication circumventing checks on the data. This can cause the frame to pass checks and be considered a valid frame of a different type. (CVE-2020-24588) Frames used for authentication and key management between the AP and connected clients. Some clients may take these redirected frames masquerading as control mechanisms from the AP. (CVE-2020-26139) A vulnerability was found in Linux kernel's WiFi implementation. An attacker within wireless range can inject a control packet fragment where the kernel does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. (CVE-2020-26141) A flaw was found in ath10k_htt_rx_proc_rx_frag_ind_hl in drivers/net/wireless/ath/ath10k/htt_rx.c in the Linux kernel WiFi implementations, where it accepts a second (or subsequent) broadcast fragments even when sent in plaintext and then process them as full unfragmented frames. The highest threat from this vulnerability is to integrity. (CVE-2020-26145) A flaw was found in ieee80211_rx_h_defragment in net/mac80211/rx.c in the Linux Kernel's WiFi implementation. This vulnerability can be abused to inject packets or exfiltrate selected fragments when another device sends fragmented frames, and the WEP, CCMP, or GCMP data-confidentiality protocol is used. The highest threat from this vulnerability is to integrity. (CVE-2020-26147) A flaw was found in the Linux kernel in certs/blacklist.c, When signature entries for EFI_CERT_X509_GUID are contained in the Secure Boot Forbidden Signature Database, the entries are skipped. This can cause a security threat and breach system integrity, confidentiality and even lead to a denial of service problem. (CVE-2020-26541) A vulnerability was found in the bluez, where Passkey Entry protocol used in Secure Simple Pairing (SSP), Secure Connections (SC) and LE Secure Connections (LESC) of the Bluetooth Core Specification is vulnerable to an impersonation attack where an active attacker can impersonate the initiating device without any previous knowledge. (CVE-2020-26558) A flaw was found in the Linux kernel. Improper access control in BlueZ may allow an authenticated user to potentially enable information disclosure via adjacent access. The highest threat from this vulnerability is to data confidentiality and integrity. (CVE-2021-0129) A flaw was found in the Linux kernel's KVM implementation, where improper handing of the VM_IO|VM_PFNMAP VMAs in KVM bypasses RO checks and leads to pages being freed while still accessible by the VMM and guest. This flaw allows users who can start and control a VM to read/write random pages of memory, resulting in local privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity, and system availability. (CVE-2021-22543) A flaw was found in the Linux kernel's handling of the removal of Bluetooth HCI controllers. This flaw allows an attacker with a local account to exploit a race condition, leading to corrupted memory and possible privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-32399) A use-after-free flaw was found in hci_send_acl in the bluetooth host controller interface (HCI) in Linux kernel, where a local attacker with an access rights could cause a denial of service problem on the system The issue results from the object hchan, freed in hci_disconn_loglink_complete_evt, yet still used in other places. The highest threat from this vulnerability is to data integrity, confidentiality and system availability. (CVE-2021-33034) The canbus filesystem in the Linux kernel contains an information leak of kernel memory to devices on the CAN bus network link layer. An attacker with the ability to dump messages on the CAN bus is able to learn of uninitialized stack values by dumbing messages on the can bus. (CVE-2021-34693) An out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in the f2fs module in the Linux kernel. A bounds check failure allows a local malicious user to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability. (CVE-2021-3506) A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the system. (CVE-2021-3564) A flaw use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in the way user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call hci_unregister_dev() together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(), hci_get_auth_info(). A privileged local user could use this flaw to crash the system or escalate their privileges on the system. (CVE-2021-3573) A flaw was found in the Linux kernels NFC implementation, A NULL pointer dereference and BUG leading to a denial of service can be triggered by a local unprivileged user causing a kernel panic. (CVE-2021-38208). 8) - x86_64 3. Description: The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. NetBSD of An authentication vulnerability exists in the kernel.Service operation interruption (DoS) It may be in a state. 8) - x86_64 3.

A physically proximate attacker could possibly use this issue to inject or decrypt packets. (CVE-2020-26141) Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation accepted plaintext fragments in certain situations. A physically proximate attacker could use this issue to inject packets. (CVE-2020-26145) Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation could reassemble mixed encrypted and plaintext fragments. A physically proximate attacker could possibly use this issue to inject packets or exfiltrate selected fragments. (CVE-2020-26147) Or Cohen discovered that the SCTP implementation in the Linux kernel contained a race condition in some situations, leading to a use-after-free condition. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-23133) Or Cohen and Nadav Markus discovered a use-after-free vulnerability in the nfc implementation in the Linux kernel. A privileged local attacker could use this issue to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-23134) Manfred Paul discovered that the extended Berkeley Packet Filter (eBPF) implementation in the Linux kernel contained an out-of-bounds vulnerability. A local attacker could use this issue to execute arbitrary code. (CVE-2021-31440) Piotr Krysiuk discovered that the eBPF implementation in the Linux kernel did not properly prevent speculative loads in certain situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2021-31829) It was discovered that a race condition in the kernel Bluetooth subsystem could lead to use-after-free of slab objects. An attacker could use this issue to possibly execute arbitrary code. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33034) It was discovered that an out-of-bounds (OOB) memory access flaw existed in the f2fs module of the Linux kernel. A local attacker could use this issue to cause a denial of service (system crash). (CVE-2021-3506) Mathias Krause discovered that a null pointer dereference existed in the Nitro Enclaves kernel driver of the Linux kernel. A local attacker could use this issue to cause a denial of service or possibly execute arbitrary code. (CVE-2021-3543) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 21.04: linux-image-5.11.0-1009-kvm 5.11.0-1009.9 linux-image-kvm 5.11.0.1009.9 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.
