CVE-2026-102711 is a vulnerability in Eclipse Threadx
Published on September 29, 2026
Out-of-bounds Read and Unverified Entry Pointers in the ThreadX Module Loader
In Eclipse ThreadX versions 6.0.1 through 6.5.2.202603, the Module Manager loaders take a module image without its length and trust the sizes and offsets in its preamble. A crafted module image can declare a code size larger than the image to read, or gain access to, the memory that follows it, and can place its entry points outside its code.
Vulnerability Analysis
CVE-2026-102711 can be exploited with local system access, and requires small amount of user privileges. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have no impact on confidentiality and integrity and availability.
Weakness Types
Out-of-bounds Read
The software reads data past the end, or before the beginning, of the intended buffer. Typically, this can allow attackers to read sensitive information from other memory locations or cause a crash. A crash can occur when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string. The expected sentinel might not be located in the out-of-bounds memory, causing excessive data to be read, leading to a segmentation fault or a buffer overflow. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent read operation then produces undefined or unexpected results.
Insufficient Verification of Data Authenticity
The software does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
Improper Validation of Specified Quantity in Input
The product receives input that is expected to specify a quantity (such as size or length), but it does not validate or incorrectly validates that the quantity has the required properties.
