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： drm/amdkfd：在 CRIU 恢复过程中正确获取队列缓冲区 当 从 中拆分出来时， 被遗漏了。因此， 未能填充 结构中的缓冲区字段，这可能导致后续代码在期望这些字段非空时出现问题。 修复方法是：在 中添加对 的正确调用，同时修正该函数中遗漏的正确类型转换（这些转换与上述问题同时被遗漏）。 （此修复从提交 88ed96abbbe27b70193544fbc1ee06448c274714 中 cherry-pick 而来）

Vulnerability Title
drm/amdkfd: Properly acquire queue buffers in CRIU restore
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Properly acquire queue buffers in CRIU restore When kfd_queue_acquire_buffers() was split off from set_queue_properties_from_user(), set_queue_properties_from_criu() was missed. Thus, set_queue_properties_from_criu() is not filling out the buffer fields of queue_properties, which can come up when subsequent code expects them to be non-null. Add the proper call to kfd_queue_acquire_buffers(), and also use the right cast types in set_queue_properties_from_criu() (which were missed at the same time) (cherry picked from commit 88ed96abbbe27b70193544fbc1ee06448c274714)
