CVE-2026-101990

Name of the Vulnerable Software and Affected Versions Juniper Networks Junos OS (affected versions not specified) Juniper Networks Junos OS Evolved (affected versions not specified)

Description A stack-based buffer overflow occurs in the routing protocol daemon (rpd). This issue allows a remote configured BGP peer to trigger an rpd crash or achieve remote code execution on Junos OS by sending a flow-spec update that is selected for re-advertisement. A stack-based buffer overflow is a condition where a program writes more data to a buffer located on the stack than the buffer is allocated to hold, potentially overwriting adjacent memory.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
