Juniper Junos OS kernel: **[KEV]** Improper isolation in the Junos kernel lets a local attacker with shell access inject

Impact

**[KEV]** Improper isolation in the Junos kernel lets a local attacker with shell access inject arbitrary code — exploited in the wild to implant persistent backdoors on routers

Who can reach it

Local, shell access

What to do

Junos upgrade fleet-wide with routing failover; the in-the-wild usage means affected devices need forensic verification, not just patching
