      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: hci_event: fix LE list UAF on reset\n\nhci_cc_reset() clears the LE accept and resolving lists without taking\nhdev->lock. Other command-complete handlers serialize updates to these\nlists with that lock, and the debugfs readers hold it while walking them.\n\nThis permits the reset completion and a debugfs read to interleave as\nfollows:\n\n  hci_rx_work                 debugfs reader\n  -----------                 --------------\n                              lock hdev->lock\n                              fetch current entry\n  list_del(entry)\n  kfree(entry)\n                              read entry fields\n\nThe reader then dereferences a freed list entry and may follow its stale\nnext pointer.\n\nKASAN reported:\n\n  BUG: KASAN: slab-use-after-free in white_list_show+0x15f/0x180\n  Read of size 1 at addr ffff8881015dab16 by task poc/95\n\n  Call Trace:\n   white_list_show+0x15f/0x180\n   seq_read_iter+0x3ff/0x1190\n   seq_read+0x267/0x3d0\n   vfs_read+0x177/0xa20\n   ksys_read+0xf7/0x1c0\n\n  Allocated by task 91:\n   hci_bdaddr_list_add+0x1a6/0x3a0\n   hci_cc_le_add_to_accept_list+0xab/0x140\n   hci_cmd_complete_evt+0x26c/0x9a0\n   hci_event_packet+0x454/0xb20\n   hci_rx_work+0x293/0x730\n\n  Freed by task 90:\n   kfree+0x131/0x3c0\n   hci_bdaddr_list_clear+0xd8/0x160\n   hci_cc_reset+0x28a/0x370\n   hci_cmd_complete_evt+0x26c/0x9a0\n   hci_event_packet+0x454/0xb20\n   hci_rx_work+0x293/0x730\n\nTake hdev->lock around both list clears.
