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： rust_binder：在线程退出时重新调度节点引用计数更新当线程通过退出时，其待处理的工作项会被取消。如果线程在持有待处理的节点引用计数增量（例如，作为延迟工作项推送到该线程）时退出，此前该引用计数增量会被丢弃，因为和当时是空操作（no-ops）。丢弃引用计数更新会导致节点的交付状态与计数状态不同步，用户空间将无法收到通知。这可能导致：当所有外部引用被释放后，该节点永远无法从进程的节点树中释放。修复方法是：为和实现，使得在线程退出时，将待处理的引用计

Vulnerability Title

rust_binder: reschedule node refcount update on thread exit

Source: CVE Program / CVE List V5

Vulnerability Description

In the Linux kernel, the following vulnerability has been resolved: rust_binder: reschedule node refcount update on thread exit When a thread exits via BINDER_THREAD_EXIT, its pending work items are cancelled. If a thread exits while holding a pending node refcount increment (e.g. pushed as deferred work to that thread), the refcount increment was previously dropped because Node::cancel() and NodeWrapper::cancel() were no-ops. Dropping the refcount update leaves the node's delivery state and count state desynchronized, and userspace will not receive the notification, which can cause the node to never be freed from the process's nodes tree when all external references are dropped. Fix this by implementing DeliverToRead::cancel() for Node and NodeWrapper to move the pending refcount update to the process's work queue on thread exit so another thread can deliver it to userspace.
