Title
Bluetooth: L2CAP: do not leave dangling sk pointer on error in l2cap_sock_create()
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: do not leave dangling sk pointer on error in l2cap_sock_create()
bt_sock_alloc() allocates the sk object and attaches it to the provided
sock object. On error l2cap_sock_alloc() frees the sk object, but the
dangling pointer is still attached to the sock object, which may create
use-after-free in other code.

No race the attacker cannot influence and no unpredictable memory layout is required.\nPR:L - `l2cap_sock_create()` imposes no capability check for SOCK_SEQPACKET/SOCK_STREAM/SOCK_DGRAM \u2014 `CAP_NET_RAW` gates only SOCK_RAW and `CAP_NET_BIND_SERVICE` applies later at `bind()` \u2014 so any unprivileged local user on a Bluetooth-enabled system can reach the allocation failure path.\nUI:N - The attacker triggers the entire sequence themselves with a single syscall under self-induced memory pressure; no victim must open a file, pair a device, or take any other action.\nS:U - The freed `struct sock`, the stale `sock-\u003esk` reference, and every downstream effect remain within the kernel\u0027s own security authority \u2014 no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - `sock-\u003esk` is left pointing at slab memory freed by `sk_free()`, and `__sock_create()`\u0027s error path skips the `sock-\u003esk = NULL` clearing in `__sock_release()` (it sits inside the `if (ops)` block after `sock-\u003eops = NULL`), so any subsequent dereference reads freed memory \u2014 as KASAN-confirmed in the parent fix, `__sock_gen_cookie()` performs an 8-byte read of the dead object, and the attacker can reclaim that `l2cap_pinfo`-sized slab object by heap spray to control and disclose its contents.\nI:H - The same dangling pointer yields a write primitive, not just a read: `__sock_gen_cookie()` issues `atomic64_cmpxchg(\u0026sk-\u003esk_cookie, ...)` into the freed object at a fixed offset, corrupting whatever attacker-groomed structure has reclaimed that slot \u2014 a classic use-after-free write usable for control-flow hijacking.\nA:H - Use of the freed `struct sock` corrupts the slab allocator and produces oops or panic even when not weaponized; additionally the `DEBUG_NET_WARN_ONCE(sock-\u003esk, ...)` added to `__sock_create()` for exactly this bug class fires on CONFIG_DEBUG_NET kernels, which is fatal under `panic_on_warn`."
