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，以下漏洞已得到修复： 输入： synaptics-rmi4 - 将 F54 工作线程的错误状态传递至 V4L2 队列 此前， 函数会等待工作线程完成，但忽略其是否成功。如果工作线程因超时或寄存器读取失败等原因而失败，队列线程会静默地返回成功状态，从而将过期或未初始化的内存数据传递到用户空间。 修复方式：在 中新增一个 字段，用于存储工作线程的退出状态。在 中，在工作线程完成后检查该字段；若检测到错误，则将该缓冲区标记为 状态。

Vulnerability Title
Input: synaptics-rmi4 - propagate F54 worker errors to V4L2 queue
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: Input: synaptics-rmi4 - propagate F54 worker errors to V4L2 queue Previously, rmi_f54_buffer_queue() waited for the worker thread to finish but ignored whether it succeeded. If the worker failed (e.g., due to a timeout or register read failure), the queue thread would silently return success, delivering stale or uninitialized memory to userspace. Add a 'report_error' field to struct f54_data to store the worker's exit status. Check this field in rmi_f54_buffer_queue() after the worker finishes, and mark the buffer as VB2_BUF_STATE_ERROR if an error occurred.
