Overview

CVE-2025-68229 is a known-severity vulnerability. It was published on December 16, 2025.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

scsi: target: tcm_loop: Fix segfault in tcm_loop_tpg_address_show()

If the allocation of tl_hba->sh fails in tcm_loop_driver_probe() and we

attempt to dereference it in tcm_loop_tpg_address_show() we will get a

segfault, see below for an example. So, check tl_hba->sh before

dereferencing it.

Unable to allocate struct scsi_host
