An Improper Validation of Consistency within Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-adjacent configured BGP peer to cause a denial of service by sending a specifically malformed BGP MCAST-TREE update and this NLRI is then attempted to be readvertised.CVE-2026-101948juniper networksjunos os+1EPSS score0.46%
A NULL Pointer Dereference vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a remote unauthenticated BGP peer to cause a denial of service via a specific BGP FlowSpec update received by an affected BGP session.CVE-2026-102082juniper networksjunos osEPSS score0.34%
An Improper Handling of Missing Special Element vulnerability in the SSL plugin of Juniper Networks Junos OS on SRX Series allows a network-based, unauthenticated attacker to cause a Denial-of-Service (DoS).
This issue is will occur when 'ssl-proxy' is configured on SRX platforms and during a TLS session-resumption attempt a specifically malformed TLS message is received. This results in an invalid pointer access and PFE crash which causes a temporary loss of traffic forwarding until the PFE automatically recovers. The exact internal timing to trigger this issue is outside the attacker's direct control.This issue affects Junos OS on SRX Series:
* All versions before 23.2R2-S5;
* 23.4 versions before 23.4R2-S5;
* 24.2 versions before 24.2R2-S2;
* 24.4 versions before 24.4R2.CVE-2026-102081juniper networksjunos osEPSS score0.37%
A Missing Release of Memory after Effective Lifetime vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a complete Denial-of-Service (DoS).
On SRX4000 Series, and SRX5000 Series with SPC3, and MX Series with SPC3, when one or more specific application services like ALGs, IDP/DPI, APPID, SECINTEL, AAMW or AppQoE are configured, a high connections per second churn will cause PFE memory to leak. If the memory is exhausted traffic processing will be impacted.
Use the CLI command show security monitoring to monitor the memory utilization of the PFEs on the FPCs.
This issue affects Junos OS on SRX Series and MX Series:
* 23.4 versions from 23.4R2-S3 before 23.4R2-S7;
* 24.2 versions from 24.2R2 before 24.2R2-S3;
* 24.4 versions before 24.4R2-S3;
* 25.2 versions before 25.2R1-S2, 25.2R2.CVE-2026-102080juniper networksjunos osEPSS score0.18%
An Improper Resource Locking vulnerability in the clock synchronization daemon (clksyncd) of Juniper Networks Junos OS on MX Series allows a unauthenticated, logically adjacent attacker to cause a Denial-of-Service (DoS).
If a SyncE or PTP upstream node sends a malformed message to an MX device equipped with SCBE3, a false 19.44MHz alarm is generated on the master RE. This leads to persistent RE switchovers and a clksyncd process crash. This issue is outside the attacker's direct control as it's a race condition.
This issue affects Junos OS on MX Series:
* All versions before 23.2R2-S7.7;
* 23.4 versions before 23.4R2-S8.13;
* 24.2 versions before 24.2R2-S5.5;
* 24.4 versions before 24.4R2-S4;
* 25.2 versions before 25.2R2-S1;
* 25.4 versions before 25.4R1-S2.CVE-2026-102079juniper networksjunos osEPSS score0.66%
An OS command injection vulnerability in the CLI of Juniper Networks Junos OS allows a local, low privileged attacker to take complete control of the device.
A specific 'request csds' command doesn't sanitize user provided input so that it can be interpreted as a command. This allows unintended command execution with root privileges, which can lead to unauthorized system access or modification.
This issue affects Junos OS:
* 24.4 versions before 24.4R2-S4;
* 25.2 versions before 25.2R2-S1;
* 25.4 versions before 25.4R1-S3;
This issue does not affect Junos OS releases before 24.4R1.
