In the Linux kernel, the following vulnerability has been resolved:
scsi: target: iscsi: Fix timeout on deleted connection
NOPIN response timer may expire on a deleted connection and crash with such logs:
Did not receive response to NOPIN on CID: 0, failing connection for I_T Nexus (null),i,0x00023d000125,iqn.2017-01.com.iscsi.target,t,0x3d
BUG: Kernel NULL pointer dereference on read at 0x00000000 NIP strlcpy+0x8/0xb0 LR iscsitfillcxntimeouterrstats+0x5c/0xc0 [iscsitargetmod] Call Trace: iscsithandlenopinresponsetimeout+0xfc/0x120 [iscsitargetmod] calltimerfn+0x58/0x1f0 runtimersoftirq+0x740/0x860 _dosoftirq+0x16c/0x420 irqexit+0x188/0x1c0 timer_interrupt+0x184/0x410
That is because nopin response timer may be re-started on nopin timer expiration.
Stop nopin timer before stopping the nopin response timer to be sure that no one of them will be re-started.
