Target-core completes those commands\nasynchronously, so VHOST_SET_MEM_TABLE can replace the memory table while\nan in-flight command still retains response iovecs translated through the\nold table.\n\nIf the old mapping is reused after VHOST_SET_MEM_TABLE returns, command\ncompletion can write the response to an unrelated userspace object.\n\nFlush the vhost-scsi backend after vhost_dev_ioctl() handles a device\nioctl.  This waits for in-flight commands that can still use the old\nresponse iovecs before the ioctl returns.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/22598f55a4c2b510b3df5e69e563387a963222ae","tags":[]},{"url":"https://git.kernel.org/stable/c/6c1b802e36b05ebd9d41686c4dce6f06966af469","tags":[]},{"url":"https://git.kernel.org/stable/c/981c97d09c6b9560bb12dcc41f11ce59b1a48e97","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
