Summary
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: msft: fix slab-use-after-free in msft_do_close() Tying the msft->data lifetime to hdev by freeing it in hci_release_dev() to fix the following case: [use] msft_do_close() msft = hdev->msft_data; if (!msft) ...(1) <- passed. return; mutex_lock(&msft->filter_lock); ...(4) <- used after freed. [free] msft_unregister() msft = hdev->msft_data; hdev->msft_data = NULL; ...(2) kfree(msft); ...(3) <- msft is freed. ================================================================== BUG: KASAN: slab-use-after-free in __mutex_lock_common kernel/locking/mutex.c:587 [inline] BUG: KASAN: slab-use-after-free in __mutex_lock+0x8f/0xc30 kernel/locking/mutex.c:752 Read of size 8 at addr ffff888106cbbca8 by task kworker/u5:2/309

The vulnerable `msft_do_close()` path is only reachable through local device-lifecycle operations.\nAC:L - The attacker controls both sides of the race \u2014 it creates the HCI device, arms the close path (the 2-second `power_off` auto-off delayed work, or an injected HCI Hardware Error that queues `error_reset`), then tears the transport down to run `msft_unregister()` concurrently. The window is wide (no shared lock between the free and the use) and the attempt is infinitely retryable.\nPR:L - An unprivileged local user reaching the Bluetooth HCI device-management interfaces can drive both the adapter power-down path and the transport teardown that frees `msft_data`; no real root in the initial namespace is required to win this race. This matches the privilege level assigned to the equivalent HCI teardown use-after-frees (CVE-2024-53208, CVE-2024-58013, CVE-2024-58241).\nUI:N - The race is driven entirely by the attacker\u0027s own sequence of device-lifecycle and power-state operations. No victim action or interaction is needed at any point.\nS:U - The freed object, the corrupted heap, and the resulting compromise all reside within the kernel\u0027s own security authority. There is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - After the freed `msft_data` slab is reallocated with sprayed data, `msft_do_close()` walks `msft-\u003ehandle_map` and reads `handle_data-\u003emgmt_handle` from attacker-controlled memory and feeds it to `idr_find()`, yielding an arbitrary kernel read primitive. Any use-after-free of this shape enables disclosure of arbitrary kernel memory.\nI:H - The same list walks perform `list_del()` on attacker-controlled `list_head` pointers \u2014 an arbitrary write of pointer values to attacker-chosen kernel addresses \u2014 followed by `kfree()` of an attacker-chosen pointer, and `mutex_lock()` on a corrupted `filter_lock`. These are classic primitives for control-flow hijacking and local privilege escalation.\nA:H - Even without successful exploitation, the slab-use-after-free reliably corrupts kernel state and causes an oops or panic, as demonstrated by the KASAN report in `__mutex_lock` from `kworker/u5:2`. This is a complete denial of service that the attacker can trigger at will."

This matches the privilege level assigned to the equivalent HCI teardown use-after-frees (CVE-2024-53208, CVE-2024-58013, CVE-2024-58241).\\nUI:N - The race is driven entirely by the attacker\u0027s own sequence of device-lifecycle and power-state operations. No victim action or interaction is needed at any point.\\nS:U - The freed object, the corrupted heap, and the resulting compromise all reside within the kernel\u0027s own security authority. There is no crossing of a VM, IOMMU, or sandbox boundary.\\nC:H - After the freed `msft_data` slab is reallocated with sprayed data, `msft_do_close()` walks `msft-\u003ehandle_map` and reads `handle_data-\u003emgmt_handle` from attacker-controlled memory and feeds it to `idr_find()`, yielding an arbitrary kernel read primitive. Any use-after-free of this shape enables disclosure of arbitrary kernel memory.\\nI:H - The same list walks perform `list_del()` on attacker-controlled `list_head` pointers \\u2014 an arbitrary write of pointer values to attacker-chosen kernel addresses \\u2014 followed by `kfree()` of an attacker-chosen pointer, and `mutex_lock()` on a corrupted `filter_lock`. These are classic primitives for control-flow hijacking and local privilege escalation.\\nA:H - Even without successful exploitation, the slab-use-after-free reliably corrupts kernel state and causes an oops or panic, as demonstrated by the KASAN report in `__mutex_lock` from `kworker/u5:2`. This is a complete denial of service that the attacker can trigger at will.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"bf6a4e30ffbd9e9ef8934582feb937f6532f8b68\", \"lessThan\": \"e3880b531b68f98d3941d83f2f6dd11cf4fd6b76\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bf6a4e30ffbd9e9ef8934582feb937f6532f8b68\", \"lessThan\": \"a85a60e62355e3bf4802dead7938966824b23940\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bf6a4e30ffbd9e9ef8934582feb937f6532f8b68\", \"lessThan\": \"4f1de02de07748da80a8178879bc7a1df37fdf56\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"bf6a4e30ffbd9e9ef8934582feb937f6532f8b68\", \"lessThan\": \"10f9f426ac6e752c8d87bf4346930ba347aaabac\", \"versionType\": \"git\"}], \"programFiles\": [\"net/bluetooth/hci_core.c\", \"net/bluetooth/msft.c\", \"net/bluetooth/msft.h\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.12\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.12\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.1.91\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.31\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8.10\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.8.*\"}, {\"status\": \"unaffected\", \"version\": \"6.9\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/bluetooth/hci_core.c\", \"net/bluetooth/msft.c\", \"net/bluetooth/msft.h\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/e3880b531b68f98d3941d83f2f6dd11cf4fd6b76\"}, {\"url\": \"https://git.kernel.org/stable/c/a85a60e62355e3bf4802dead7938966824b23940\"}, {\"url\": \"https://git.kernel.org/stable/c/4f1de02de07748da80a8178879bc7a1df37fdf56\"}, {\"url\": \"https://git.kernel.org/stable/c/10f9f426ac6e752c8d87bf4346930ba347aaabac\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nBluetooth: msft: fix slab-use-after-free in msft_do_close()\\n\\nTying the msft-\u003edata lifetime to hdev by freeing it in\\nhci_release_dev() to fix the following case:\\n\\n[use]\\nmsft_do_close()\\n  msft = hdev-\u003emsft_data;\\n  if (!msft)                      ...(1) \u003c- passed.\\n    return;\\n  mutex_lock(\u0026msft-\u003efilter_lock); ...(4) \u003c- used after freed.\\n\\n[free]\\nmsft_unregister()\\n  msft = hdev-\u003emsft_data;\\n  hdev-\u003emsft_data = NULL;         ...(2)\\n  kfree(msft);                    ...(3) \u003c- msft is freed.\\n\\n==================================================================\\nBUG: KASAN: slab-use-after-free in __mutex_lock_common\\nkernel/locking/mutex.c:587 [inline]\\nBUG: KASAN: slab-use-after-free in __mutex_lock+0x8f/0xc30\\nkernel/locking/mutex.c:752\\nRead of size 8 at addr ffff888106cbbca8 by task kworker/u5:2/309\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.1.91\", \"versionStartIncluding\": \"5.12\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.31\", \"versionStartIncluding\": \"5.12\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.8.10\", \"versionStartIncluding\": \"5.12\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.9\", \"versionStartIncluding\": \"5.12\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-08-05T11:31:34.945Z\"}}}",
