Summary
Descriptions

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
