Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/cma: Fix kmemleak in rdma_core observed during blktests nvme/rdma use siw
When running blktests nvme/rdma, the following kmemleak issue will appear.
kmemleak: Kernel memory leak detector initialized (mempool available:36041)
kmemleak: Automatic memory scanning thread started
kmemleak: 2 new suspected memory leaks (see /sys/kernel/debug/kmemleak)
kmemleak: 8 new suspected memory leaks (see /sys/kernel/debug/kmemleak)
kmemleak: 17 new suspected memory leaks (see /sys/kernel/debug/kmemleak)
kmemleak: 4 new suspected memory leaks (see /sys/kernel/debug/kmemleak)
