In the Linux kernel, the following vulnerability has been resolved:
nfc: llcp: Fix memleak in nfc_llcp_send_ui_frame().
syzbot reported various memory leaks related to NFC, struct
nfc_llcp_sock, sk_buff, nfc_dev, etc. [0]
The leading log hinted that nfc_llcp_send_ui_frame() failed
to allocate skb due to sock_error(sk) being -ENXIO.
ENXIO is set by nfc_llcp_socket_release() when struct
nfc_llcp_local is destroyed by local_cleanup().
The problem is that there is no synchronisation between
nfc_llcp_send_ui_frame() and local_cleanup(), and skb
could be put into local->tx_queue after it was purged in
local_cleanup():
CPU1 CPU2
---- ----
nfc_llcp_send_ui_frame() local_cleanup()
|- do { '
|- pdu = nfc_alloc_send_skb(..., &err)
| .
| |- nfc_llcp_socket_release(local, false, ENXIO);
| |- skb_queue_purge(&local->tx_queue); |
| ' |
|- skb_queue_tail(&local->tx_queue, pdu); |
... |
|- pdu = nfc_alloc_send_skb(..., &err) |
^._________________________________.'
local_cleanup() is called for struct nfc_llcp_local only
after nfc_llcp_remove_local() unlinks it from llcp_devices.
If we hold local->tx_queue.lock then, we can synchronise
the thread and nfc_llcp_send_ui_frame().
Let's do that and check list_empty(&local->list) before
queuing skb to local->tx_queue in nfc_llcp_send_ui_frame().

kernel: nfc: llcp: Fix memleak in nfc_llcp_send_ui_frame()

CVE-2026-23150 [MEDIUM] kernel: nfc: llcp: Fix memleak in nfc_llcp_send_ui_frame()
kernel: nfc: llcp: Fix memleak in nfc_llcp_send_ui_frame()
In the Linux kernel, the following vulnerability has been resolved:
nfc: llcp: Fix memleak in nfc_llcp_send_ui_frame().
syzbot reported various memory leaks related to NFC, struct
nfc_llcp_sock, sk_buff, nfc_dev, etc. [0]
The leading log hinted that nfc_llcp_send_ui_frame() failed
to allocate skb due to sock_error(sk) being -ENXIO.
ENXIO is set by nfc_llcp_socket_release() when struct
nfc_llcp_local is destroyed by local_cleanup().
The problem is that there is no synchronisation between
nfc_llcp_send_ui_frame() and local_cleanup(), and skb
could be put into local->tx_queue after it was purged in
local_cleanup():
