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： net/rds：根据连接最终使用的传输层来设定其路径集的大小 函数在决定某个连接是否应由回环（loopback）传输层来处理（即当目标地址是主机自身的地址时）之前，就依据调用方提供的传输层计算了路径数量（ ）。对于向本地地址发送数据的 RDS/TCP 套接字，系统会进行这种回环传输层的替换。然而，替换之后，路径初始化循环仍然会为 TCP 传输层配置的 个路径执行，并为每个路径分配一个有序工作队列（workqueue）。而 实际上只为路径 0 提供传输层数据。 在 执行清

Vulnerability Title
net/rds: size a connection's path set by the transport it ends up with
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: net/rds: size a connection's path set by the transport it ends up with __rds_conn_create() computes npaths from the caller's transport before it decides whether a connection to one of the host's own addresses is to be handled by the loopback transport instead. That substitution is what an RDS/TCP socket sending to a local address gets, and after it the path init loop still runs for the TCP transport's RDS_MPATH_WORKERS paths and allocates an ordered workqueue for each, while rds_loop_conn_alloc() only ever provides transport data for path 0. rds_conn_destroy() sizes its teardown from c_trans, by then the loopback transport, so it visits path 0 only - and rds_conn_path_destroy() would skip the other paths anyway, since it returns before destroy_workqueue() for a path without transport data. kfree(c_path) then drops the last pointers to seven workqueues. That repeats for every such connection, on every netns teardown or module unload, and every distinct local destination address is a separate connection. Recompute npaths once the transport is final, so that creation and destruction agree on the set of paths. The c_path array stays sized for the caller's transport; the unused entries are freed with it.
