Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： accel/amdxdna：修复设备移除期间 IOMMU 域生命周期竞态问题 当启用 模式时， 会释放 。如果在设备移除之后调用了 ，该函数可能会尝试访问 ，从而导致“释放后使用”（use-after-free）错误。 通过添加将 的释放作为一个受管释放动作来修复该竞态条件，使其生命周期由 DRM 管理，确保在所有受管资源被释放之前始终保持有效。

Vulnerability Title
accel/amdxdna: Fix iommu domain lifetime race during device removal
Source: CVE Program / CVE List V5
Vulnerability 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.
