In the Linux kernel, the following vulnerability has been resolved:
scsi: target: file: Use kzalloc_flex for aio_cmd
The target_core_file doesn't initialize the aio_cmd->iocb for the
ki_write_stream. When a write command fd_execute_rw_aio() is executed,
we may get a bogus ki_write_stream value, causing unintended write
failure status when checking iocb->ki_write_stream > max_write_streams
in the block device.
Let's just use kzalloc_flex when allocating the aio_cmd and let
ki_write_stream=0 to fix this issue.
