|---|---|---|---|---|---|---|---|---|
| CVE-2023-24548 | Med | 0.34 | 5.3 | 0.00 | Aug 29, 2023 | On affected platforms running Arista EOS with VXLAN configured, malformed or truncated packets received over a VXLAN tunnel and forwarded in hardware can cause egress ports to be unable to forward packets. The device will continue to be susceptible to the issue until remediation… | ||
| CVE-2025-8870 | Med | 0.32 | 4.9 | 0.00 | Nov 14, 2025 | On affected platforms running Arista EOS, certain serial console input might result in an unexpected reload of the device.153 | ||
| CVE-2025-7048 | Med | 0.28 | 4.3 | 0.00 | Jan 6, 2026 | On affected platforms running Arista EOS with MACsec configuration, a specially crafted packet can cause the MACsec process to terminate unexpectedly. Continuous receipt of these packets with certain MACsec configurations can cause longer term disruption of dataplane traffic. | ||
| CVE-2024-7095 | Med | 0.28 | 4.3 | 0.00 | Jan 10, 2025 | On affected platforms running Arista EOS with SNMP configured, if “snmp-server transmit max-size” is configured, under some circumstances a specially crafted packet can cause the snmpd process to leak memory. This may result in the snmpd process being terminated (causing… | ||
| CVE-2025-3456 | Low | 0.25 | 3.8 | 0.00 | Aug 25, 2025 | On affected platforms running Arista EOS, the global common encryption key configuration may be logged in clear text, in local or remote accounting logs. Knowledge of both the encryption key and protocol specific encrypted secrets from the device running-config could then be… | ||
| CVE-2020-25686 | Low | 0.24 | 3.7 | 0.05 | Jan 20, 2021 | A flaw was found in dnsmasq before version 2.83. When receiving a query, dnsmasq does not check for an existing pending request for the same name and forwards a new request. By default, a maximum of 150 pending queries can be sent to upstream servers, so there can be at most 150… | ||
| CVE-2020-25685 | Low | 0.24 | 3.7 | 0.02 | Jan 20, 2021 | A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in forward.c:reply_query(), which is the forwarded query that matches the reply, by only using a weak hash of the query name. Due to the weak hash (CRC32 when dnsmasq is… | ||
| CVE-2020-25684 | Low | 0.24 | 3.7 | 0.04 | Jan 20, 2021 | A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in the forward.c:reply_query() if the reply destination address/port is used by the pending forwarded queries. However, it does not use the address/port to retrieve the… | ||
| CVE-2015-6815 | Low | 0.23 | 3.5 | 0.01 | Jan 31, 2020 | The process_tx_desc function in hw/net/e1000.c in QEMU before 2.4.0.1 does not properly process transmit descriptor data when sending a network packet, which allows attackers to cause a denial of service (infinite loop and guest crash) via unspecified vectors. | ||
| CVE-2025-2826 | Low | 0.17 | 2.6 | 0.00 | May 27, 2025 | n affected platforms running Arista EOS, ACL policies may not be enforced. IPv4 ingress ACL, MAC ingress ACL, or IPv6 standard ingress ACL enabled on one or more ethernet or LAG interfaces may result in ACL policies not being enforced for ingress packets. This can cause incoming… | ||
| CVE-2017-18017 | Cri | 0.04 | 9.8 | 0.53 | Jan 3, 2018 | The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the… | ||
| CVE-2015-5165 | 0.01 | — | 0.13 | Aug 12, 2015 | The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors. | |||
| CVE-2015-3209 | 0.01 | — | 0.10 | Jun 15, 2015 | Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUS_STARTPACKET set and then a crafted packet with TXSTATUS_DEVICEOWNS set. | |||
| CVE-2015-8236 | 0.00 | — | 0.04 | Nov 19, 2015 | Arista EOS before 4.11.12, 4.12 before 4.12.11, 4.13 before 4.13.14M, 4.14 before 4.14.5FX.5, and 4.15 before 4.15.0FX1.1 allows remote attackers to execute arbitrary code as root by leveraging management-plane access, aka Bug 138716. | |||
| CVE-2015-3214 | 0.00 | — | 0.02 | Aug 31, 2015 | The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index. |
