CVE-2024-47695 Information

Description

In the Linux kernel the following vulnerability has been resolved:

RDMA/rtrs-clt: Reset cid to con_num - 1 to stay in bounds

In the function init_conns() after the create_con() and create_cm() for loop if something fails. In the cleanup for loop after the destroy tag we access out of bound memory because cid is set to clt_path->s.con_num.

This commits resets the cid to clt_path->s.con_num - 1 to stay in bounds in the cleanup loop later.
