Title
Bluetooth: MGMT: Fix possible crash on mgmt_index_removed
Summary
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: Fix possible crash on mgmt_index_removed If mgmt_index_removed is called while there are commands queued on cmd_sync it could lead to crashes like the bellow trace: 0x0000053D: __list_del_entry_valid_or_report+0x98/0xdc 0x0000053D: mgmt_pending_remove+0x18/0x58 [bluetooth] 0x0000053E: mgmt_remove_adv_monitor_complete+0x80/0x108 [bluetooth] 0x0000053E: hci_cmd_sync_work+0xbc/0x164 [bluetooth] So while handling mgmt_index_removed this attempts to dequeue commands passed as user_data to cmd_sync.

The stale entry is then processed deterministically in the same worker loop.\nPR:L - Reaching the mgmt command handlers requires a trusted control socket (CAP_NET_ADMIN), which on real deployments is held by non-root Bluetooth service accounts (bluetoothd, Android\u0027s Bluetooth stack), so a compromised unprivileged service reaches it; the power-off half is additionally reachable by ordinary desktop/session users via rfkill and D-Bus. Consistent with prior kernel.org scoring of the same mgmt_pending UAF class (CVE-2025-38118, CVE-2026-31511).\nUI:N - The full sequence is issued by the attacker\u0027s own process through the mgmt socket; no action by another user or victim is needed.\nS:U - The use-after-free corrupts kernel heap state within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed mgmt_pending_cmd is re-read after being reclaimed, and mgmt_cmd_complete() sends cmd-\u003eparam/cmd-\u003eparam_len from the stale allocation back to the attacker\u0027s socket, disclosing arbitrary reallocated kernel heap contents.\nI:H - mgmt_pending_remove() performs list_del on the freed and attacker-reclaimable object, yielding a controlled kernel write primitive, and sock_put(cmd-\u003esk) decrements a refcount through a stale pointer \u2014 both leveragable for privilege escalation via heap grooming.\nA:H - The reported failure is a kernel crash in __list_del_entry_valid_or_report from mgmt_pending_remove; any unexploited attempt reliably oopses or panics the kernel."
