Apache Nuttx vulnerabilities

CVE-2025-48769 [HIGH] CWE-416 CVE-2025-48769: Use After Free vulnerability was discovered in fs/vfs/fs_rename code of the Apache NuttX RTOS, that Use After Free vulnerability was discovered in fs/vfs/fs_rename code of the Apache NuttX RTOS, that due recursive implementation and single buffer use by two different pointer variables allowed arbitrary user provided size buffer reallocation and write to the previously freed heap chunk, that in specific cases could cause unintended virtual filesystem

CVE-2025-48768 [MEDIUM] CWE-763 CVE-2025-48768: Release of Invalid Pointer or Reference vulnerability was discovered in fs/inode/fs_inoderemove code 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 Servi

CVE-2025-47868 [CRITICAL] CWE-122 CVE-2025-47868: Out-of-bounds Write resulting in possible Heap-based Buffer Overflow vulnerability was discovered in Out-of-bounds Write resulting in possible Heap-based Buffer Overflow vulnerability was discovered in tools/bdf-converter font conversion utility that is part of Apache NuttX RTOS repository. This standalone program is optional and neither part of NuttX RTOS nor Applications runtime, but active bdf-converter users may be affected when this tool is

CVE-2025-47869 [CRITICAL] CWE-119 CVE-2025-47869: Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability was discovered Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability was discovered in Apache NuttX RTOS apps/exapmles/xmlrpc application. In this example application device stats structure that stored remotely provided parameters had hardcoded buffer size which could lead to buffer overflow. Structure members buffers were updated

CVE-2025-35003 [CRITICAL] CWE-119 CVE-2025-35003: Improper Restriction of Operations within the Bounds of a Memory Buffer and Stack-based Buffer Overf Improper Restriction of Operations within the Bounds of a Memory Buffer and Stack-based Buffer Overflow vulnerabilities were discovered in Apache NuttX RTOS Bluetooth Stack (HCI and UART components) that may result in system crash, denial of service, or arbitrary code execution, after receiving maliciously crafted packets. NuttX's Bluetooth HCI/U

CVE-2021-26461 [CRITICAL] CWE-190 CVE-2021-26461: Apache Nuttx Versions prior to 10.1.0 are vulnerable to integer wrap-around in functions malloc, rea Apache Nuttx Versions prior to 10.1.0 are vulnerable to integer wrap-around in functions malloc, realloc and memalign. This improper memory assignment can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution.

CVE-2020-17528 [CRITICAL] CWE-787 CVE-2020-17528: Out-of-bounds Write vulnerability in TCP stack of Apache NuttX (incubating) versions up to and inclu Out-of-bounds Write vulnerability in TCP stack of Apache NuttX (incubating) versions up to and including 9.1.0 and 10.0.0 allows attacker to corrupt memory by supplying arbitrary urgent data pointer offsets within TCP packets including beyond the length of the packet.

CVE-2020-17529 [CRITICAL] CWE-787 CVE-2020-17529: Out-of-bounds Write vulnerability in TCP Stack of Apache NuttX (incubating) versions up to and inclu Out-of-bounds Write vulnerability in TCP Stack of Apache NuttX (incubating) versions up to and including 9.1.0 and 10.0.0 allows attacker to corrupt memory by supplying and invalid fragmentation offset value specified in the IP header. This is only impacts builds with both CONFIG_EXPERIMENTAL and CONFIG_NET_TCP_REASSEMBLY build flags enabled.

CVE-2020-1939 [CRITICAL] CWE-476 CVE-2020-1939: The Apache NuttX (Incubating) project provides an optional separate "apps" repository which contains The Apache NuttX (Incubating) project provides an optional separate "apps" repository which contains various optional components and example programs. One of these, ftpd, had a NULL pointer dereference bug. The NuttX RTOS itself is not affected. Users of the optional apps repository are affected only if they have enabled ftpd. Versions 6.15 to 8.2 a
