CVE-2026-21914 is a high-severity improper locking vulnerability in the GTP plugin of Juniper Networks Junos OS on SRX Series devices. An unauthenticated attacker can send a malformed GTP Modify Bearer Request message that causes a lock to be acquired and never released, leading to a watchdog timeout and FPC crash. This results in a denial-of-service condition causing complete traffic outage until the device recovers. The vulnerability affects multiple Junos OS versions prior to specific patched releases across versions 22.4R3-S8 through 25.2R2. Exploitation requires no authentication or user interaction and can be performed remotely over the network. There are no known exploits in the wild as of now. The CVSS v3.1 score is 7.
