  "description": "In the Linux kernel, the following vulnerability has been resolved:  scsi: target: tcmu: Fix possible page UAF  tcmu_try_get_data_page() looks up pages under cmdr_lock, but it does not take refcount properly and just returns page pointer. When tcmu_try_get_data_page() returns, the returned page may have been freed by tcmu_blocks_release().  We need to get_page() under cmdr_lock to avoid concurrent tcmu_blocks_release().",
