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： drm/amdkfd: 修复 destroy_queue_cpsch 中的 UAF（Use-After-Free，释放后使用）竞态条件 wait_on_destroy_queue() 函数在等待队列恢复时会释放锁，这允许并发执行的销毁操作提前释放队列内存。为解决该问题，引入 is_being_destroyed 标志，用于序列化销毁操作，避免竞态条件发生。
