  "description": "In the Linux kernel, the following vulnerability has been resolved:  scsi: pm8001: Fix abort all task initialization  In pm80xx_send_abort_all(), the n_elem field of the ccb used is not initialized to 0. This missing initialization sometimes lead to the task completion path seeing the ccb with a non-zero n_elem resulting in the execution of invalid dma_unmap_sg() calls in pm8001_ccb_task_free(), causing a crash such as:  [  197.676341] RIP: 0010:iommu_dma_unmap_sg\u002B0x6d/0x280 [  197.700204] RSP: 0018:ffff889bbcf89c88 EFLAGS: 00010012 [  197.705485] RAX: dffffc0000000000 RBX: 0000000000000000 RCX: ffffffff83d0bda0 [  197.712687] RDX: 0000000000000002 RSI: 0000000000000000 RDI: ffff88810dffc0d0 [  197.719887] RBP: 0000000000000000 R08: 0000000000000000 R09: ffff8881c790098b [  197.727089] R10: ffffed1038f20131 R11: 0000000000000001 R12: 0000000000000000 [  197.734296] R13: ffff88810dffc0d0 R14: 0000000000000010 R15: 0000000000000000 [  197.741493] FS:  0000000000000000(0000) GS:ffff889bbcf80000(0000) knlGS:0000000000000000 [  197.749659] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [  197.755459] CR2: 00007f16c1b42734 CR3: 0000000004814000 CR4: 0000000000350ee0 [  197.762656] Call Trace: [  197.765127]  \u003CIRQ\u003E [  197.767162]  pm8001_ccb_task_free\u002B0x5f1/0x820 [pm80xx] [  197.772364]  ? do_raw_spin_unlock\u002B0x54/0x220 [  197.776680]  pm8001_mpi_task_abort_resp\u002B0x2ce/0x4f0 [pm80xx] [  197.782406]  process_oq\u002B0xe85/0x7890 [pm80xx] [  197.786817]  ? lock_acquire\u002B0x194/0x490 [  197.790697]  ? handle_irq_event\u002B0x10e/0x1b0 [  197.794920]  ? mpi_sata_completion\u002B0x2d70/0x2d70 [pm80xx] [  197.800378]  ? __wake_up_bit\u002B0x100/0x100 [  197.804340]  ? lock_is_held_type\u002B0x98/0x110 [  197.808565]  pm80xx_chip_isr\u002B0x94/0x130 [pm80xx] [  197.813243]  tasklet_action_common.constprop.0\u002B0x24b/0x2f0 [  197.818785]  __do_softirq\u002B0x1b5/0x82d [  197.822485]  ? do_raw_spin_unlock\u002B0x54/0x220 [  197.826799]  __irq_exit_rcu\u002B0x17e/0x1e0 [  197.830678]  irq_exit_rcu\u002B0xa/0x20 [  197.834114]  common_interrupt\u002B0x78/0x90 [  197.840051]  \u003C/IRQ\u003E [  197.844236]  \u003CTASK\u003E [  197.848397]  asm_common_interrupt\u002B0x1e/0x40  Avoid this issue by always initializing the ccb n_elem field to 0 in pm8001_send_abort_all(), pm8001_send_read_log() and pm80xx_send_abort_all().",
