Severity ?
7.6 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: bluetooth/hci: disallow setting handle bigger than HCI_CONN_HANDLE_MAX Syzbot hit warning in hci_conn_del() caused by freeing handle that was not allocated using ida allocator. This is caused by handle bigger than HCI_CONN_HANDLE_MAX passed by hci_le_big_sync_established_evt(), which makes code think it's unset connection. Add same check for handle upper bound as in hci_conn_set_handle() to prevent warning.

Per Bluetooth scoring convention this is Adjacent.\\nAC:L - No race, no memory-layout grooming, and no timing dependency \\u2014 a single HCI event carrying a connection handle above 0x0eff deterministically creates a bogus \\\"unset\\\" hci_conn whose teardown always hits the ida_free WARN.\\nPR:N - LE ACL connections and broadcast/PA sync require no pairing, bonding, or authentication, and no local account is needed; the attacker only needs to be an unauthenticated peer in range of a host with LE Audio/ISO enabled.\\nUI:N - The event handlers run automatically in `hci_rx_work` as part of normal LE connection and broadcast-sync processing; no victim action is required.\\nS:U - The corruption is confined to the kernel\u0027s own Bluetooth connection and IDA state within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\\nC:L - The `WARN(1, ...)` in `ida_free()` emits a full register and stack backtrace containing kernel text and heap addresses, giving a bounded KASLR-defeating info leak; there is no arbitrary read primitive.\\nI:L - The erroneous `ida_free()` desynchronizes `hdev-\u003eunset_handle_ida`, releasing an ID still owned by another connection so the same handle can be issued twice and `hci_conn_hash_lookup_handle()` resolves to the wrong connection; the out-of-range handle also corrupts the PB/BC flag bits of outgoing ACL/ISO headers. This is bounded kernel-state modification, not an arbitrary write.\\nA:H - The bug reliably triggers a kernel WARNING, which is a panic on the many deployments (Android, CI, hardened distros) running with `panic_on_warn`, and the resulting duplicate-handle confusion persistently disrupts Bluetooth connection handling.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"f7e83f2278f06b577e3c92ea2f4e8e8c6fc72a8f\", \"lessThan\": \"2ae8d7742a09c275872e670c53337b3dcedaa11c\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"84cb0143fb8a03bf941c7aaedd56c938c99dafad\", \"lessThan\": \"4970e48f83dbd21d2a6a7cdaaafc2a71f7f45dc4\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"181a42edddf51d5d9697ecdf365d72ebeab5afb0\", \"lessThan\": \"d311036696fed778301d08a71a4bef737b86d8c5\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"181a42edddf51d5d9697ecdf365d72ebeab5afb0\", \"lessThan\": \"1cc18c2ab2e8c54c355ea7c0423a636e415a0c23\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"e9f708beada55426c8d678e2f46af659eb5bf4f0\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"6.6.2\", \"lessThan\": \"6.6.39\", \"versionType\": \"semver\"}, {\"status\": \"affected\", \"version\": \"6.5.12\", \"lessThan\": \"6.6\", \"versionType\": \"semver\"}], \"programFiles\": [\"net/bluetooth/hci_conn.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"6.7\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"6.7\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.6.39\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.9.9\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.9.*\"}, {\"status\": \"unaffected\", \"version\": \"6.10\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/bluetooth/hci_conn.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/2ae8d7742a09c275872e670c53337b3dcedaa11c\"}, {\"url\": \"https://git.kernel.org/stable/c/4970e48f83dbd21d2a6a7cdaaafc2a71f7f45dc4\"}, {\"url\": \"https://git.kernel.org/stable/c/d311036696fed778301d08a71a4bef737b86d8c5\"}, {\"url\": \"https://git.kernel.org/stable/c/1cc18c2ab2e8c54c355ea7c0423a636e415a0c23\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nbluetooth/hci: disallow setting handle bigger than HCI_CONN_HANDLE_MAX\\n\\nSyzbot hit warning in hci_conn_del() caused by freeing handle that was\\nnot allocated using ida allocator.\\n\\nThis is caused by handle bigger than HCI_CONN_HANDLE_MAX passed by\\nhci_le_big_sync_established_evt(), which makes code think it\u0027s unset\\nconnection.\\n\\nAdd same check for handle upper bound as in hci_conn_set_handle() to\\nprevent warning.\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.39\", \"versionStartIncluding\": \"6.6.2\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.9.9\", \"versionStartIncluding\": \"6.7\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.10\", \"versionStartIncluding\": \"6.7\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionStartIncluding\": \"6.5.12\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-08-05T11:35:49.667Z\"}}}",
