Summary
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix slab-use-after-free in l2cap_connect() Extend a critical section to prevent chan from early freeing. Also make the l2cap_connect() return type void. Nothing is using the returned value but it is ugly to return a potentially freed pointer. Making it void will help with backports because earlier kernels did use the return value. Now the compile will break for kernels where this patch is not a complete fix.

Per kernel scoring guidance Bluetooth is Adjacent.\nAC:L - The attacker drives both sides of the race \u2014 it sends the L2CAP_CONN_REQ that allocates the channel and independently forces the link abort/disconnect that runs l2cap_conn_del on the other workqueue \u2014 and can repeat the attempt indefinitely at no cost. No precondition lies outside the attacker\u0027s control.\nPR:N - l2cap_bredr_sig_cmd() processes L2CAP_CONN_REQ on the fixed signalling CID 0x0001 with no authentication, and l2cap_connect() explicitly bypasses hci_conn_check_link_mode() for the always-listening SDP PSM 0x0001. An unpaired, unauthenticated remote device needs no credentials on the target.\nUI:N - Exploitation only requires the target to be connectable, which is the default state for phones, headsets, car head units, laptops and embedded devices with Bluetooth enabled. No victim action of any kind is needed.\nS:U - The corruption is of kernel slab memory handled by the kernel itself; the vulnerable component and the impacted component share the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed chan is read and its fields (imtu, max_tx, tx_win, fcs, retrans/monitor timeouts) are packed into an L2CAP Configuration Request sent back over the air, leaking reallocated slab contents directly to the attacker, and chan-\u003econn is dereferenced as a pointer taken from freed memory, giving an arbitrary-read primitive once the slab is groomed.\nI:H - After the free the code performs set_bit(CONF_REQ_SENT, \u0026chan-\u003econf_state) and chan-\u003enum_conf_req++, writing into the freed slab, and the object holds the ops function-pointer table and data/conn pointers, so heap spraying yields a write primitive and control-flow hijack potential.\nA:H - This is a slab use-after-free that reliably produces KASAN splats, memory corruption, and kernel oops/panic, and it can be re-triggered repeatedly by an unauthenticated in-range attacker to keep the system down."

Per kernel scoring guidance Bluetooth is Adjacent.\\nAC:L - The attacker drives both sides of the race \\u2014 it sends the L2CAP_CONN_REQ that allocates the channel and independently forces the link abort/disconnect that runs l2cap_conn_del on the other workqueue \\u2014 and can repeat the attempt indefinitely at no cost. No precondition lies outside the attacker\u0027s control.\\nPR:N - l2cap_bredr_sig_cmd() processes L2CAP_CONN_REQ on the fixed signalling CID 0x0001 with no authentication, and l2cap_connect() explicitly bypasses hci_conn_check_link_mode() for the always-listening SDP PSM 0x0001. An unpaired, unauthenticated remote device needs no credentials on the target.\\nUI:N - Exploitation only requires the target to be connectable, which is the default state for phones, headsets, car head units, laptops and embedded devices with Bluetooth enabled. No victim action of any kind is needed.\\nS:U - The corruption is of kernel slab memory handled by the kernel itself; the vulnerable component and the impacted component share the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\\nC:H - The freed chan is read and its fields (imtu, max_tx, tx_win, fcs, retrans/monitor timeouts) are packed into an L2CAP Configuration Request sent back over the air, leaking reallocated slab contents directly to the attacker, and chan-\u003econn is dereferenced as a pointer taken from freed memory, giving an arbitrary-read primitive once the slab is groomed.\\nI:H - After the free the code performs set_bit(CONF_REQ_SENT, \u0026chan-\u003econf_state) and chan-\u003enum_conf_req++, writing into the freed slab, and the object holds the ops function-pointer table and data/conn pointers, so heap spraying yields a write primitive and control-flow hijack potential.\\nA:H - This is a slab use-after-free that reliably produces KASAN splats, memory corruption, and kernel oops/panic, and it can be re-triggered repeatedly by an unauthenticated in-range attacker to keep the system down.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"73ffa904b78287f6acf8797e040150aa26a4af4a\", \"lessThan\": \"8629a65a48890769c47ebc9b6e57c02a80a8975e\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"73ffa904b78287f6acf8797e040150aa26a4af4a\", \"lessThan\": \"cfe560c7050bfb37b0d2491bbe7cd8b59e77fdc5\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"73ffa904b78287f6acf8797e040150aa26a4af4a\", \"lessThan\": \"826af9d2f69567c646ff46d10393d47e30ad23c6\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"73ffa904b78287f6acf8797e040150aa26a4af4a\", \"lessThan\": \"4d7b41c0e43995b0e992b9f8903109275744b658\", \"versionType\": \"git\"}], \"programFiles\": [\"net/bluetooth/l2cap_core.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"3.0\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"3.0\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.1.178\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.32\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8.11\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.8.*\"}, {\"status\": \"unaffected\", \"version\": \"6.9\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/bluetooth/l2cap_core.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/8629a65a48890769c47ebc9b6e57c02a80a8975e\"}, {\"url\": \"https://git.kernel.org/stable/c/cfe560c7050bfb37b0d2491bbe7cd8b59e77fdc5\"}, {\"url\": \"https://git.kernel.org/stable/c/826af9d2f69567c646ff46d10393d47e30ad23c6\"}, {\"url\": \"https://git.kernel.org/stable/c/4d7b41c0e43995b0e992b9f8903109275744b658\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nBluetooth: L2CAP: Fix slab-use-after-free in l2cap_connect()\\n\\nExtend a critical section to prevent chan from early freeing.\\nAlso make the l2cap_connect() return type void.
