[ Upstream commit f002612b9d ] This happens when BMC doesn't return any data and the code is trying to print the value of data[2]. Getting following crash: [ 484.728410] Unable to handle kernel NULL pointer dereference at virtual address 00000002 [ 484.736496] pgd = ffff0000094a2000 [ 484.739885] [00000002] *pgd=00000047fcffe003, *pud=00000047fcffd003, *pmd=0000000000000000 [ 484.748158] Internal error: Oops: 96000005 [#1] SMP [...] [ 485.101451] Call trace: [...] [ 485.188473] [<ffff000000a46e68>] msg_done_handler+0x668/0x700 [ipmi_ssif] [ 485.195249] [<ffff000000a456b8>] ipmi_ssif_thread+0x110/0x128 [ipmi_ssif] [ 485.202038] [<ffff0000080f1430>] kthread+0x108/0x138 [ 485.206994] [<ffff0000080838e0>] ret_from_fork+0x10/0x30 [ 485.212294] Code: aa1903e1 aa1803e0 b900227f 95fef6a5 (39400aa3) Adding a check to validate the data len before printing data[2] to fix this issue.
