Nuttx

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 rename/move operation results. [CVSS 8.1 HIGH]

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. [CVSS 6.5 MEDIUM]

Buffer overflow vulnerability in the Apache NuttX RTOS xmlrpc example application where device statistics structures use hardcoded buffer sizes that do not account for the CONFIG_XMLRPC_STRINGSIZE configuration parameter, allowing remote attackers to overflow memory without authentication. This affects Apache NuttX RTOS versions 6.22 through 12.8.x, with a critical CVSS score of 9.8 indicating high severity across confidentiality, integrity, and availability. The vulnerability is particularly dangerous because developers may have copied the vulnerable example code into production implementations, extending the attack surface beyond the example application itself.

A buffer overflow vulnerability (CVSS 9.8). Critical severity with potential for significant impact on affected systems.

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). Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

Apache Nuttx Versions prior to 10.1.0 are vulnerable to integer wrap-around in functions malloc, realloc and memalign. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

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. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

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. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

The Apache NuttX (Incubating) project provides an optional separate "apps" repository which contains various optional components and example programs. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This NULL Pointer Dereference vulnerability could allow attackers to crash the application by dereferencing a null pointer.

An issue was discovered in NuttX before 7.27. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
