What to do
AI-suggested
A fix has been implemented in the Linux kernel to manage the lifetime of xdna->domain properly. Users should apply the official kernel updates that include this patch. Since this is a kernel-level vulnerability, upgrading to a patched kernel version is the recommended mitigation. Patch status is not explicitly stated here; check the vendor or distribution advisory for the exact fixed versions and update instructions.
Description
A use-after-free vulnerability in the Linux kernel's amdxdna driver was fixed. The issue occurs when force_iova mode is enabled and the device is removed, leading to a race condition where xdna->domain is freed prematurely. This can cause subsequent access to freed memory, resulting in potential system compromise. The fix involves managing the lifetime of xdna->domain through DRM-managed release actions to prevent premature freeing.
