Linux Kernel Vulnerability in AMD Graphics Driver

CVE-2026-53376

What is CVE-2026-53376?

A security vulnerability has been identified in the AMD graphics driver of the Linux kernel that allows for improper input validation in the kfd_ioctl_get_process_apertures_new function. This flaw could potentially lead to unexpected behavior in the system’s handling of process and memory management for GPU resources. By lacking an upper bound check for the number of nodes, malicious actors could exploit this vulnerability to manipulate kernel behavior, potentially leading to system instability or other unforeseen consequences.
