What is CVE-2025-38700?

A vulnerability exists in the Linux kernel's SCSI subsystem, specifically in the initialization of iscsi_conn->dd_data. If a memory allocation for ib_fast_reg_mr fails during iSER setup, it leads to a system panic due to an uninitialized pointer dereference. This flaw occurs because iscsi_conn->dd_data is set regardless of memory allocation, resulting in potential crashes when terminating connections. The issue has been rectified by ensuring that iscsi_conn->dd_data is assigned only after a successful memory allocation.
