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.

avoid concurrent access and a check to fail repeated requests.
Also, if the mmap entry insert fails for the WC, free the Doorbell
page index mapped for the WC page.
