CVE-2023-54184 - Vulnerability Details

Description

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.
BUG: kernel NULL pointer dereference, address: 0000000000000140
RIP: 0010:sbitmap_queue_clear+0x3a/0xa0
Call Trace:
