Summary
In the Linux kernel, the following vulnerability has been resolved:
raid10: cleanup memleak at raid10_make_request
If raid10_read_request or raid10_write_request registers a new
request and the REQ_NOWAIT flag is set, the code does not
free the malloc from the mempool.
unreferenced object 0xffff8884802c3200 (size 192):
comm "fio", pid 9197, jiffies 4298078271
hex dump (first 32 bytes):
