Quick assessment

Affected
Linux Linux
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，已修复以下漏洞： drm/amdkfd：检查 allocate_sdma_queue 和 restore_sdma_id 的边界值 allocate_sdma_queue 提供了一个选项，允许指定 SDMA 队列 ID（CRIU 会使用此功能）。此前，我们未对该值进行边界检查。 现在确认该值小于最大队列数。
