Low risk16th percentile - higher than 16% of all known CVEs
Summary
An out-of-bounds access in the RDMA rtrs-clt subsystem of the Linux kernel was found in init_conns(). In the cleanup loop after an error, the cid variable is set to con_num, leading to out-of-bounds access.
Risk Assessment
This can lead to system crashes or unpredictable behavior, especially in RDMA environments.
Recommendation
Install a Linux kernel update containing the fix that resets cid to con_num - 1 to stay in bounds.
Original NVD description (English source)
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.
