Title
scsi: pm8001: Fix abort all task initialization
Summary
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+0x6d/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] <IRQ> [ 197.767162] pm8001_ccb_task_free+0x5f1/0x820 [pm80xx] [ 197.772364] ? do_raw_spin_unlock+0x54/0x220 [ 197.776680] pm8001_mpi_task_abort_resp+0x2ce/0x4f0 [pm80xx] [ 197.782406] process_oq+0xe85/0x7890 [pm80xx] [ 197.786817] ? lock_acquire+0x194/0x490 [ 197.790697] ? handle_irq_event+0x10e/0x1b0 [ 197.794920] ? mpi_sata_completion+0x2d70/0x2d70 [pm80xx] [ 197.800378] ? __wake_up_bit+0x100/0x100 [ 197.804340] ? lock_is_held_type+0x98/0x110 [ 197.808565] pm80xx_chip_isr+0x94/0x130 [pm80xx] [ 197.813243] tasklet_action_common.constprop.0+0x24b/0x2f0 [ 197.818785] __do_softirq+0x1b5/0x82d [ 197.822485] ? do_raw_spin_unlock+0x54/0x220 [ 197.826799] __irq_exit_rcu+0x17e/0x1e0 [ 197.830678] irq_exit_rcu+0xa/0x20 [ 197.834114] common_interrupt+0x78/0x90 [ 197.840051] </IRQ> [ 197.844236] <TASK> [ 197.848397] asm_common_interrupt+0x1e/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().
