Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Avoid repeated requests to allocate WC pages Applications can request multiple WC pages for the same ucontext.

Also, if the mmap entry insert fails for the WC, free the Doorbell page index mapped for the WC page.
