Details

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