The vulnerability is reached entirely through local interfaces — a `write()` of an MGMT_OP_SET_POWERED command on an AF_BLUETOOTH HCI control socket racing a local `ioctl(HCIDEVDOWN)`; no over-the-air Bluetooth traffic is involved in either side of the race.\nAC:L - The attacker controls both sides of the race and can spin the pair (mgmt SET_POWERED write, HCIDEVDOWN ioctl) in a tight loop until the work item fires against the freed command, exactly as the syzbot reproducer does.\nPR:L - The path is gated on CAP_NET_ADMIN, which in real deployments is held by unprivileged network-facing service accounts (bluetoothd, Android's bluetooth UID) rather than by root, making this a service-privilege-to-kernel escalation; this matches the scoring of the structurally identical CVE-2024-58013 in the same file.\nUI:N - The attacker triggers both the command submission and the device-down teardown directly; no action by any other user or victim is needed.\nS:U - The use-after-free corrupts kernel slab memory and is exploited within the same kernel security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - `set_powered_sync()` reads the `cmd->param` pointer out of freed slab memory and dereferences it; if the reallocated object is attacker-sprayed this yields a controlled-address read, and the freed `cmd->sk` is subsequently used to build a response, enabling kernel memory disclosure.\nI:H - Beyond the read, `mgmt_set_powered_complete()` calls `mgmt_pending_remove()` on the freed command, performing a `list_del()` unlink through attacker-controllable pointers — a classic arbitrary-write primitive leading to control-flow hijack.\nA:H - The slab use-after-free reliably faults in the `hci_cmd_sync_work` kworker (KASAN-confirmed by syzbot), producing a kernel oops/panic and taking down the Bluetooth workqueue and potentially the whole system." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "net/bluetooth/mgmt.c" ], "versions": [ { "version": "275f3f64870245b06188f24bdf917e55a813d294", "lessThan": "cdfc818ffdfeb8266351ed59b6d884056009a095", "status": "affected", "versionType": "git" }, { "version": "275f3f64870245b06188f24bdf917e55a813d294", "lessThan": "95f7a972194ad20696c36523b54c19a3567e0697", "status": "affected", "versionType": "git" }, { "version": "275f3f64870245b06188f24bdf917e55a813d294", "lessThan": "6b75f32bce90c085c89c45761373d940fdcff68c", "status": "affected", "versionType": "git" }, { "version": "275f3f64870245b06188f24bdf917e55a813d294", "lessThan": "87819234aa1d2a0cb0f962fabb335e798f5ec8b2", "status": "affected", "versionType": "git" }, { "version": "275f3f64870245b06188f24bdf917e55a813d294", "lessThan": "0b882940665ca2849386ee459d4331aa2f8c4e7d", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "net/bluetooth/mgmt.c" ], "versions": [ { "version": "5.17", "status": "affected" }, { "version": "0", "lessThan": "5.17", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.120", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.64", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11.11", "lessThanOrEqual": "6.11.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.2", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.13", "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": "5.17", "versionEndExcluding": "6.1.120" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "6.6.64" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "6.11.11" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "6.12.2" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "6.13" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/cdfc818ffdfeb8266351ed59b6d884056009a095" }, { "url": "https://git.kernel.org/stable/c/95f7a972194ad20696c36523b54c19a3567e0697" }, { "url": "https://git.kernel.org/stable/c/6b75f32bce90c085c89c45761373d940fdcff68c" }, { "url": "https://git.kernel.org/stable/c/87819234aa1d2a0cb0f962fabb335e798f5ec8b2" }, { "url": "https://git.kernel.org/stable/c/0b882940665ca2849386ee459d4331aa2f8c4e7d" } ], "title": "Bluetooth: MGMT: Fix slab-use-after-free Read in set_powered_sync", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "cvssV3_1": { "scope": "UNCHANGED", "version": "3.1", "baseScore": 7.8, "attackVector": "LOCAL", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "integrityImpact": "HIGH", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "HIGH" } }, { "other": { "type": "ssvc", "content": { "id": "CVE-2024-53208", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "version": "2.0.3", "timestamp": "2025-03-06T16:07:48.553528Z" } } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-416", "description": "CWE-416 Use After Free" } ] } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-03-06T16:14:32.855Z" } }, { "title": "CVE Program Container", "references": [ { "url": "https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T20:47:36.970Z" } } ] } }
