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： remoteproc: qcom_q6v5_adsp：修复设备节点引用泄漏 当调用 of_parse_phandle_with_args() 时，调用方有责任调用 of_node_put() 以释放设备节点的引用。 而在 adsp_map_carveout 中，并未释放该引用，从而导致引用泄漏。
