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： HID: asus: 重构两个工作队列及初始化序列 在 hid-asus 驱动程序中发现了多个问题： asus_raw_event() 函数中未检查数据大小 asus_probe 函数在失败时未进行妥善的资源清理 asus_probe 函数中存在可能的 use-after-free（使用已释放内存）漏洞 使用了多个工作队列执行本可由一个工作队列完成的任务 在原子上下文中调用了可能导致进程睡眠的函数 向键盘控制器发送了大小不正确的数据包 解决方案：将两个工作队列合并为一个

Vulnerability Title
HID: asus: refactor the two workqueues and init sequence
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: HID: asus: refactor the two workqueues and init sequence Multiple issues have been found within the hid-asus driver: - unchecked size in asus_raw_event() - unclean teardown of asus_probe on failure - possible use-after-free in asus_probe - multiple workqueue used for jobs where one was enough - sleeping calls in atomic context - packets of incorrect size being sent to the keyboard controller Join the two workqueues into one reusing the stopping mechanism of the brightness workqueue, use the joined workqueue to also move the asus_wmi_send_event() sleeping call away from atomic context and add a size check in asus_raw_event().
