CVE-2025-48768 Apache Software Foundation CVE debrief

Who should care

Users of filesystem-based services with write access exposed over the network, such as FTP, should assess their exposure and prioritize remediation. This includes operators, platform administrators, vulnerability management teams, and security teams who need to verify affected versions, assess exposure, and apply necessary updates or mitigations. Upgrading to version 12.10.0 is recommended to address the vulnerability.

Why it matters

CVE-2025-48768 is a medium-severity vulnerability in Apache NuttX RTOS that can lead to Denial of Service or disruption of filesystem-based services. Users of affected versions should prioritize remediation by upgrading to version 12.10.0.

• Denial of Service (DoS) via NULL pointer dereference or debug assert trigger
• Potential disruption of filesystem-based services with write access exposed over the network
• Need for verification of affected versions and exposure in the environment

Technical summary

The vulnerability is a Release of Invalid Pointer or Reference issue in the fs/inode/fs_inoderemove code of Apache NuttX RTOS. It allows root filesystem inode removal, potentially leading to a debug assert trigger, NULL pointer dereference, or Denial of Service. The issue affects Apache NuttX RTOS versions from 10.0.0 before 12.10.0. Users of filesystem-based services with write access exposed over the network, such as FTP, are affected and recommended to upgrade to version 12.10.0. The vulnerability has a medium severity

Defensive priority

Upgrade to version 12.10.0, assess exposure of filesystem-based services

Recommended defensive actions

• Upgrade to Apache NuttX RTOS version 12.10.0
• Assess exposure of filesystem-based services with write access exposed over the network
• Verify inventory of affected versions and prioritize remediation
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
