NVIDIA GPU Display Driver Linux kernel OOB write via ioctl
CVE-2026-47561 Published on September 30, 2026
NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer where the size of an ioctl input buffer is not validated, allowing an unprivileged caller to trigger an out-of-bounds write in kernel memory. A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering.
Vulnerability Analysis
CVE-2026-47561 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 be very high.
Weakness Type
What is a Memory Corruption Vulnerability?
The software writes data past the end, or before the beginning, of the intended buffer. Typically, this can result in corruption of data, a crash, or code execution. 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 write operation then produces undefined or unexpected results.
CVE-2026-47561 has been classified to as a Memory Corruption vulnerability or weakness.
