In the Linux kernel, the following vulnerability has been resolved:
scsi: target: iscsit: Free cmds before session free
Commands from recovery entries are freed after session has been closed.
That leads to use-after-free at command free or NPE with such call trace:
Time2Retain timer expired for SID: 1, cleaning up iSCSI session.
