Description OSIDB Bzimport 2025-02-27 03:04:51 UTC 
In the Linux kernel, the following vulnerability has been resolved:

rdma/cxgb4: Prevent potential integer overflow on 32bit

The "gl->tot_len" variable is controlled by the user.  It comes from
process_responses().  On 32bit systems, the "gl->tot_len + sizeof(struct
cpl_pass_accept_req) + sizeof(struct rss_header)" addition could have an
integer wrapping bug.  Use size_add() to prevent this.
