the remote side of the link never controls the corrupting writes.\nAC:L - The out-of-bounds access is unconditional and deterministic \u2014 every firmware download clears and sets bits past the end of the `hci_dev` allocation, and every HCI command TX and vendor event RX repeats an OOB `test_bit` with no race or timing dependency.\nPR:L - An unprivileged local user with access to the Bluetooth stack drives the HCI traffic that repeatedly exercises the out-of-bounds flag reads, and any local trigger of device down/up re-runs the corrupting setup path; consistent with other btusb/btnxpuart driver memory CVEs scored PR:L.\nUI:N - No victim action is needed \u2014 the corruption happens automatically when the Intel PCIe Bluetooth controller is brought up, typically at boot by bluetoothd, and continues for the device lifetime.\nS:U - The out-of-bounds read/write stays within kernel heap memory under the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Out-of-bounds reads of `btintel_data` (flags bitmap and the `acpi_reset_method` pointer) pull kernel heap contents beyond the allocation, and the resulting heap corruption is of a class leverageable for arbitrary kernel memory disclosure.\nI:H - `set_bit`/`clear_bit`/`test_and_clear_bit` write past the end of the `hci_dev` allocation and a function pointer slot in that OOB region is later dereferenced and called, giving an attacker-influenceable heap write and control-flow primitive depending on adjacent slab layout.\nA:H - The out-of-bounds accesses trip KASAN/slab redzone checks and, where the 16-byte overrun crosses into a neighbouring slab object, corrupt unrelated kernel structures leading to oops or panic."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/bluetooth/btintel_pcie.c"], "versions": [{"version": "6e65a09f927566f257322358d429b267548473eb", "lessThan": "fa9e1c1b1f389a8e6d987ac6cb3e2ba04f8ec875", "status": "affected", "versionType": "git"}, {"version": "6e65a09f927566f257322358d429b267548473eb", "lessThan": "2b4545f08cc68d2fc835f5c490b36e0264750030", "status": "affected", "versionType": "git"}, {"version": "6e65a09f927566f257322358d429b267548473eb", "lessThan": "7ffaa200251871980af12e57649ad57c70bf0f43", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/bluetooth/btintel_pcie.c"], "versions": [{"version": "6.10", "status": "affected"}, {"version": "0", "lessThan": "6.10", "status": "unaffected", "versionType": "semver"}, {"version": "6.10.12", "lessThanOrEqual": "6.10.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.11.1", "lessThanOrEqual": "6.11.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.10", "versionEndExcluding": "6.10.12"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.10", "versionEndExcluding": "6.11.1"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.10", "versionEndExcluding": "6.12"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/fa9e1c1b1f389a8e6d987ac6cb3e2ba04f8ec875"}, {"url": "https://git.kernel.org/stable/c/2b4545f08cc68d2fc835f5c490b36e0264750030"}, {"url": "https://git.kernel.org/stable/c/7ffaa200251871980af12e57649ad57c70bf0f43"}], "title": "Bluetooth: btintel_pcie: Allocate memory for driver private data", "x_generator": {"engine": "bippy-1.2.0"}}, "adp": [{"metrics": [{"other": {"type": "ssvc", "content": {"timestamp": "2024-10-03T13:36:54.865418Z", "id": "CVE-2024-46869", "options": [{"Exploitation": "none"}, {"Automatable": "no"}, {"Technical Impact": "partial"}], "role": "CISA Coordinator", "version": "2.0.3"}}}], "title": "CISA ADP Vulnrichment", "providerMetadata": {"orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-10-03T13:37:08.464Z"}}]}}
