CVE-2026-89828

A flaw was found in the Linux kernel's AMD GPU (amdgpu) driver. An issue with the initialization order in the amdgpu_vram_mgr_init() function can lead to a kernel panic. If a specific registration function fails during module loading, critical data structures are not properly initialized. This can result in the system attempting to access uninitialized memory, causing a complete system crash and a denial of service.

This vulnerability is rated as Low severity because it only triggers on systems equipped with AMD GPU hardware during driver initialization failure under uncommon error conditions. Exploitation requires local administrative privileges to reload kernel drivers or depends on memory allocation exhaustion during boot, meaning unprivileged users cannot reliably trigger the crash under normal operations. Enterprise environments that do not utilize dedicated AMD graphics adapters remain unaffected.
