AutoCAD OOB Read in DWG/DXF Parser
CVE-2026-16465 Published on July 29, 2026
DWG or DXF File Parsing Out-of-Bounds Read in Autodesk AutoCAD
A maliciously crafted DWG or DXF file, when parsed through Autodesk AutoCAD, can force an Out-of-Bounds Read vulnerability. A malicious actor can leverage this vulnerability to cause a crash or disclose sensitive information.
Vulnerability Analysis
CVE-2026-16465 can be exploited with local system access, requires user interaction. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have a small impact on confidentiality, a small impact on integrity, and a high impact on availability.
Weakness Type
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.
