CVSS: 6.5EPSS: 0%CPEs: 51EXPL: 0CVE-2022-22210 – Junos OS: QFX5000 Series and MX Series: An l2alm crash leading to an FPC crash can be observed in VxLAN scenario
https://notcve.org/view.php?id=CVE-2022-22210
A NULL Pointer Dereference vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on QFX5000 Series and MX Series allows an unauthenticated adjacent attacker to cause a Denial of Service (DoS). On QFX5K Series and MX Series, when the PFE receives a specific VxLAN packet the Layer 2 Address Learning Manager (L2ALM) process will crash leading to an FPC reboot. Continued receipt of this specific packet will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS on QFX5000 Series, MX Series: 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2; 21.2 versions prior to 21.2R2-S1. This issue does not affect Juniper Networks Junos OS: All versions prior to 20.3R1; 21.1 version 21.1R1 and later versions. • https://kb.juniper.net/JSA69714 • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2022-22203
An Incorrect Comparison vulnerability in PFE of Juniper Networks Junos OS allows an adjacent unauthenticated attacker to cause a Denial of Service (DoS). On QFX5000 Series, and EX4600 and EX4650 platforms, the fxpc process will crash followed by the FPC reboot upon receipt of a specific hostbound packet. Continued receipt of these specific packets will create a sustained Denial of Service (DoS) condition. This issue only affects Juniper Networks Junos OS 19.4 version 19.4R3-S4.

https://notcve.org/view.php?id=CVE-2022-22188
An Uncontrolled Memory Allocation vulnerability leading to a Heap-based Buffer Overflow in the packet forwarding engine (PFE) of Juniper Networks Junos OS allows a network-based unauthenticated attacker to flood the device with traffic leading to a Denial of Service (DoS). The device must be configured with storm control profiling limiting the number of unknown broadcast, multicast, or unicast traffic to be vulnerable to this issue. This issue affects: Juniper Networks Junos OS on QFX5100/QFX5110/QFX5120/QFX5200/QFX5210/EX4600/EX4650 Series; 20.2 version 20.2R1 and later versions prior to 20.2R2. This issue does not affect: Juniper Networks Junos OS versions prior to 20.2R1. Una vulnerabilidad de Asignación de Memoria no Controlada conllevando a un desbordamiento del búfer en la región Heap de la memoria en el motor de reenvío de paquetes (PFE) de Juniper Networks Junos OS permite a un atacante no autenticado basado en la red inundar el dispositivo con tráfico, conllevando a una Denegación de Servicio (DoS). • https://kb.juniper.net/JSA69497 • CWE-122: Heap-based Buffer Overflow CWE-789: Memory Allocation with Excessive Size Value •
CVSS: 7.5EPSS: 0%CPEs: 158EXPL: 0CVE-2022-22174 – Junos OS: QFX5000 Series, EX4600: Device may run out of memory, causing traffic loss, upon receipt of specific IPv6 packets
https://notcve.org/view.php?id=CVE-2022-22174
A vulnerability in the processing of inbound IPv6 packets in Juniper Networks Junos OS on QFX5000 Series and EX4600 switches may cause the memory to not be freed, leading to a packet DMA memory leak, and eventual Denial of Service (DoS) condition. Once the condition occurs, further packet processing will be impacted, creating a sustained Denial of Service (DoS) condition. The following error logs may be observed using the "show heap" command and the device may eventually run out of memory if such packets are received continuously.

CVSS: 5.3EPSS: 0%CPEs: 150EXPL: 0CVE-2021-31371 – Junos OS: QFX5000 Series: Traffic from the network internal to the device (128.0.0.0) may be forwarded to egress interfaces.
https://notcve.org/view.php?id=CVE-2021-31371
Juniper Networks Junos OS uses the 128.0.0.0/2 subnet for internal communications between the RE and PFEs. It was discovered that packets utilizing these IP addresses may egress an QFX5000 Series switch, leaking configuration information such as heartbeats, kernel versions, etc. out to the Internet, leading to an information exposure vulnerability.
