CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's AMD GPU driver, specifically in the handling of IOMMU domain lifetimes during device removal. When the force_iova mode is enabled, a use-after-free condition may occur if certain functions are called post-device removal, potentially leading to system instability or crashes. Organizations utilizing affected Linux distributions with AMD GPUs should prioritize addressing this issue to ensure system reliability and security.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix iommu domain lifetime race during device removal When force_iova mode is enabled, amdxdna_remove() frees xdna->domain. If amdxdna_gem_obj_free() is called after device removal, it may attempt to access xdna->domain, resulting in a use-after-free. Fix the race by adding freeing xdna->domain as a managed release action, so its lifetime is managed by DRM and remains valid until all managed resources are released.
