{"id":"DEBIAN-CVE-2026-80764","details":"In the Linux kernel, the following vulnerability has been resolved:  Bluetooth: hci_event: fix LE list UAF on reset  hci_cc_reset() clears the LE accept and resolving lists without taking hdev-\u003elock. Other command-complete handlers serialize updates to these lists with that lock, and the debugfs readers hold it while walking them.  This permits the reset completion and a debugfs read to interleave as follows:    hci_rx_work                 debugfs reader   -----------                 --------------                               lock hdev-\u003elock                               fetch current entry   list_del(entry)   kfree(entry)                               read entry fields  The reader then dereferences a freed list entry and may follow its stale next pointer.
