In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
vhost-scsi: flush backend after device ioctls<\/p>\n
vhost-scsi translates guest response descriptors into userspace iovecs
\nwhen commands are submitted. 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.<\/p>\n
If the old mapping is reused after VHOST_SET_MEM_TABLE returns, command
\ncompletion can write the response to an unrelated userspace object.<\/p>\n
Flush 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
