CVE-2022-49053 DetailDescriptionIn 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(). Metrics
