Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
scsi: core: Fix a use-after-free
There are two .exit_cmd_priv implementations. Both implementations use resources associated with the SCSI host. Make sure that these resources are still available when .exit_cmd_priv is called by waiting inside scsi_remove_host() until the tag set has been freed.
This commit fixes the following use-after-free:
