"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nexfat: fix potential deadlock on __exfat_get_dentry_set\n\nWhen accessing a file with more entries than ES_MAX_ENTRY_NUM, the bh-array\nis allocated in __exfat_get_entry_set. The problem is that the bh-array is\nallocated with GFP_KERNEL. It does not make sense. In the following cases,\na deadlock for sbi->s_lock between the two processes may occur.\n\n CPU0 CPU1\n ---- ----\n kswapd\n balance_pgdat\n lock(fs_reclaim)\n exfat_iterate\n lock(&sbi->s_lock)\n exfat_readdir\n exfat_get_uniname_from_ext_entry\n exfat_get_dentry_set\n __exfat_get_dentry_set\n kmalloc_array\n ...\n lock(fs_reclaim)\n ...\n evict\n exfat_evict_inode\n lock(&sbi->s_lock)\n\nTo fix this, let's allocate bh-array with GFP_NOFS."
