CVE-2026-98128Hinoki check available

Target-device retention via missing failure-path release

Published Sep 25, 2026 · Updated Sep 25, 2026

A reference leak in the Linux kernel 6.1 mpi3mr SCSI driver allows attackers to retain target-device structures via unspecified vectors. mpi3mr_sas_port_add() acquires a target-device reference but jumps to out_fail without calling mpi3mr_tgtdev_put() after a later error. The condition requires SAS end-device handling followed by a port-add failure; published evidence reports retained memory only, not a crash or code execution.
