CVE-2026-23296
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: scsi: core: Fix refcount leak for tagset_refcnt This leak will cause a hang when tearing down the SCSI host. For example, iscsid hangs with the following call trace: [130120.652718] scsi_alloc_sdev: Allocation failure during SCSI scanning, some SCSI devices might not be configured PID: 2528 TASK: ffff9d0408974e00 CPU: 3 COMMAND: "iscsid" #0 [ffffb5b9c134b9e0] __schedule at ffffffff860657d4 #1 [ffffb5b9c134ba28] schedule at ffffffff86065c6f #2 [ffffb5b9c134ba40] schedule_timeout at ffffffff86069fb0 #3 [ffffb5b9c134bab0] __wait_for_common at ffffffff8606674f #4 [ffffb5b9c134bb10] scsi_remove_host at ffffffff85bfe84b #5 [ffffb5b9c134bb30] iscsi_sw_tcp_session_destroy at ffffffffc03031c4 [iscsi_tcp] #6 [ffffb5b9c134bb48] iscsi_if_recv_msg at ffffffffc0292692 [scsi_transport_iscsi] #7 [ffffb5b9c134bb98] iscsi_if_rx at ffffffffc02929c2 [scsi_transport_iscsi] #8 [ffffb5b9c134bbf0] netlink_unicast at ffffffff85e551d6 #9 [ffffb5b9c134bc38] netlink_sendmsg at ffffffff85e554ef
