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.
Weakness
The product attempts to return a memory resource to the system, but it calls the wrong release function or calls the appropriate release function incorrectly.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Nuttx | Apache | 10.0.0 (including) | 12.10.0 (excluding) |
Extended Description
This weakness can take several forms, such as:
Potential Mitigations
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, glibc in Linux provides protection against free of invalid pointers.
