  "details": "In the Linux kernel, the following vulnerability has been resolved:  erofs: add GFP_NOIO in the bio completion if needed  The bio completion path in the process context (e.g. dm-verity) will directly call into decompression rather than trigger another workqueue context for minimal scheduling latencies, which can then call vm_map_ram() with GFP_KERNEL.  Due to insufficient memory, vm_map_ram() may generate memory swapping I/O, which can cause submit_bio_wait to deadlock in some scenarios.  Trimmed down the call stack, as follows:  f2fs_submit_read_io   submit_bio                      //bio_list is initialized.     mmc_blk_mq_recovery       z_erofs_endio         vm_map_ram           __pte_alloc_kernel             __alloc_pages_direct_reclaim               shrink_folio_list                 __swap_writepage                   submit_bio_wait  //bio_list is non-NULL, hang!!!
