  "description": "In the Linux kernel, the following vulnerability has been resolved:  swiotlb: initialise restricted pool list_head when SWIOTLB_DYNAMIC=y  Using restricted DMA pools (CONFIG_DMA_RESTRICTED_POOL=y) in conjunction with dynamic SWIOTLB (CONFIG_SWIOTLB_DYNAMIC=y) leads to the following crash when initialising the restricted pools at boot-time:    | Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008   | Internal error: Oops: 0000000096000005 [#1] PREEMPT SMP   | pc : rmem_swiotlb_device_init\u002B0xfc/0x1ec   | lr : rmem_swiotlb_device_init\u002B0xf0/0x1ec   | Call trace:   |  rmem_swiotlb_device_init\u002B0xfc/0x1ec   |  of_reserved_mem_device_init_by_idx\u002B0x18c/0x238   |  of_dma_configure_id\u002B0x31c/0x33c   |  platform_dma_configure\u002B0x34/0x80  faddr2line reveals that the crash is in the list validation code:    include/linux/list.h:83   include/linux/rculist.h:79   include/linux/rculist.h:106   kernel/dma/swiotlb.c:306   kernel/dma/swiotlb.c:1695  because add_mem_pool() is trying to list_add_rcu() to a NULL \u0027mem-\u003Epools\u0027.  Fix the crash by initialising the \u0027mem-\u003Epools\u0027 list_head in rmem_swiotlb_device_init() before calling add_mem_pool().",
