CVE-2025-38399
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: Fix NULL pointer dereference in core_scsi3_decode_spec_i_port()
The function core_scsi3_decode_spec_i_port(), in its error code path, unconditionally calls core_scsi3_lunacl_undepend_item() passing the dest_se_deve pointer, which may be NULL.
This can lead to a NULL pointer dereference if dest_se_deve remains unset.
Fix this by adding a NULL check before calling core_scsi3_lunacl_undepend_item()
