Out-of-Bounds Read in NVIDIA DGX Spark MM Firmware Disclosure
CVE-2026-24225 Published on August 25, 2026
NVIDIA DGX Spark contains a vulnerability in the standalone MM firmware where an attacker could be able to cause an out-of-bounds read. A successful exploit of this vulnerability might lead to information disclosure.
Vulnerability Analysis
CVE-2026-24225 can be exploited with local system access, and requires 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 a high impact on confidentiality, with no impact on integrity and 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.
