Summary

A release of invalid pointer or reference vulnerability was discovered in the fs/inode/fs_inoderemove code of Apache NuttX RTOS, affecting versions from 10.0.0 before 12.10.0. It can lead to a debug assert trigger (disabled by default), NULL pointer dereference, or generally a Denial of Service. Users of filesystem-based services with write access exposed over the network (e.g., FTP) are affected.

Risk Assessment

The attack may cause denial of service in embedded systems, potentially disrupting critical applications.

Recommendation

Upgrade Apache NuttX RTOS to version 12.10.0, which fixes the issue, especially in environments with network-exposed filesystem-based services.

Other vulnerabilities in Apache NuttX RTOS

CVE-2025-48769High
A Use After Free vulnerability was discovered in the fs/vfs/fs_rename code of Apache NuttX RTOS, affecting versions from 7.20 before 12.11.0. Due to recursive implementation and single buffer use by two different pointer variables, arbitrary user-provided size buffer reallocation and write to previously freed heap chunk is possible, potentially causing unintended virtual filesystem rename/move results.

Original NVD description (English source)

Release of Invalid Pointer or Reference vulnerability was discovered in fs/inode/fs_inoderemove code of the Apache NuttX RTOS that allowed root filesystem inode removal leading to a debug assert trigger (that is disabled by default), NULL pointer dereference (handled differently depending on the target architecture), or in general, a Denial of Service. This issue affects Apache NuttX RTOS: from 10.0.0 before 12.10.0. Users of filesystem based services with write access that were exposed over the network (i.e. FTP) are affected and recommended to upgrade to version 12.10.0 that fixes the issue.
