An Improper Handling of Length Parameter Inconsistency vulnerability in the routing protocol daemon (rpd) process of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker to cause a denial of service via a malformed EVPN Type-3 or Type-4 route received from a configured EVPN peer and processed during re-advertisement.

CVE-2026-1059605.5 MED—
———PEAK-System PCAN contains a vulnerable operation involving a variable-length receive-record copy. The driver uses a requested or queued record count without sufficiently capping the copy to the actual caller-supplied output length.2hCVE-2026-110912—5.6%
——2In DragonFly BSD through 6.4.2 before 4bb22ff, the ARP input handlers arpintr() and in_arpinput() (sys/netinet/if_ether.c) do not validate the hardware address length (ar_hln) and protocol address length (ar_pln) fields of incoming ARP packets. in_arpreply() then uses these attacker-controlled values as memcpy lengths when copying from kernel buffers that are only 6 and 4 bytes long, resulting in an out-of-bounds read of kernel heap and stack memory that is copied into the ARP reply sent back to the requester. An unauthenticated attacker on the adjacent network can use a single crafted ARP request to disclose up to roughly 250 bytes of each type of kernel memory, including kernel pointers. This is expected to be fixed in the 6.6 stable release when that is available.4dCVE-2026-921596.5 MED22.4%
——7F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::TlmPacketizer TlmRecv_handler fixed-slot copy TlmRecv_handler copies val.getSize bytes into entry.channelSize storage without confirming that the runtime value fits. When a telemetry update for a configured channel carries a serialized value larger than that channel fixed slot, the copy overwrites adjacent channel fields and causes corrupted packetized telemetry to be emitted. This issue is fixed in version 4.3.0.5dCVE-2026-1019627.5 HIG30.6%
——9An Improper Handling of Length Parameter Inconsistency vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker sending a specifically malformed BGP EVPN multicast update which is attempted to be readvertised to cause an rpd crash.5dCVE-2026-1020544.3 MED12.0%
——4An Improper Handling of Length Parameter Inconsistency vulnerability in L2ALM of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to obtain stale PFE packet memory via VXLAN overlay-ping traffic sent to a local VTEP.5dCVE-2026-1019947.1 HIG19.0%

daemon of Juniper Networks Junos OS and Junos OS Evolved allows an attacker who can control or impersonate a configured MC-LAG ICCP peer to disclose process heap memory or cause a denial of service via a malformed ICCP message.4d
