CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtl8xxxu: fix use-after-free from rx_urb_wq on stop
rtl8xxxu arms rx_urb_wq from the RX completion path:
rtl8xxxu_rx_complete() hands the URB to rtl8xxxu_queue_rx_urb(), which
queues it on rx_urb_pending_list and, once the list grows past
RTL8XXXU_RX_URB_PENDING_WATER, schedules rx_urb_wq. The worker
rtl8xxxu_rx_urb_work() drains rx_urb_pending_list, recovers priv through
container_of, and resubmits each URB through rtl8xxxu_submit_rx_urb(),
which anchors it on rx_anchor and dereferences priv->udev.
rtl8xxxu_stop() cancels the sibling work items (c2hcmd_work, ra_watchdog,
update_beacon_work) but never cancels rx_urb_wq, so a worker armed during
the last burst of RX traffic can run rtl8xxxu_rx_urb_work() after
rtl8xxxu_disconnect() has called ieee80211_free_hw(), which frees priv,
producing a use-after-free. The window opens under active RX traffic
(pending count above the watermark) followed by a disconnect.
There are two teardown races to close:
* rtl8xxxu_queue_rx_urb() decided whether to enqueue under rx_urb_lock
but called schedule_work() after dropping the lock. A completion
that observed shutdown == false and released the lock could then call
schedule_work() after rtl8xxxu_stop() had set shutdown and
cancel_work_sync() had already returned, arming the worker to run
after the teardown. Move schedule_work() under the same !shutdown
branch so the arming decision is atomic with the shutdown check.
* rtl8xxxu_rx_urb_work() anchors every URB it drained back onto
rx_anchor through rtl8xxxu_submit_rx_urb(). A worker still running
when usb_kill_anchored_urbs(&priv->rx_anchor) returned would submit a
URB that escaped the kill. In rtl8xxxu_stop(), call
cancel_work_sync(&priv->rx_urb_wq) before the kill so the worker is
drained first.
After priv->shutdown is set under rx_urb_lock, completions can no longer
queue rx_urb_wq. cancel_work_sync() then drains the last queued or running
worker, and the following usb_kill_anchored_urbs() kills the URBs it may
have submitted.
rtl8xxxu_disconnect() is covered because ieee80211_unregister_hw()
guarantees .stop() runs for a live interface before ieee80211_free_hw()
frees priv. The probe error path needs no cancel: rx_urb_wq is
INIT_WORK()'d there but cannot have been scheduled, since no URB is
submitted before ieee80211_register_hw() succeeds.
This bug was found by static analysis. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: bound the device EEPROM address before the EFUSE copy
mt7915_mcu_get_eeprom() copies a fixed EFUSE block into the driver's
dev->mt76.eeprom.data buffer at the offset reported by the MCU response
(res->addr, a device-controlled __le32) without checking it against the
buffer size. A malicious or malfunctioning device can report an arbitrary
address and drive a 16-byte out-of-bounds write past eeprom.data.
Reject a response whose address would place the copy outside eeprom.data
before deriving the destination pointer. Devices that echo the requested
in-bounds offset are unaffected. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: bound the device EEPROM address before the EFUSE copy
mt7996_mcu_get_eeprom() derives the destination of the EFUSE/EXT block
copy from the address reported by the MCU response (event->addr, a
device-controlled __le32) and clamps only the copy length, never the
destination offset into dev->mt76.eeprom.data. A malicious or
malfunctioning device can report an arbitrary address and drive an
out-of-bounds write of up to MT7996_EXT_EEPROM_BLOCK_SIZE bytes past
eeprom.data.
Reject a response whose address would place the copy outside eeprom.data
before deriving the destination pointer. Devices that echo the requested
in-bounds offset are unaffected. |
| In the Linux kernel, the following vulnerability has been resolved:
io_uring: defer eventfd signaling when queued from a wakeup handler
io_req_local_work_add() signals the CQ ring eventfd inline when it is the
one to push the first entry onto ->work_list. For DEFER_TASKRUN rings that
add is frequently done from a waitqueue wakeup handler, where an
arbitrary waitqueue lock is held.
eventfd_signal_mask() only refuses to recurse when current->in_eventfd
is set, but that bit is set by eventfd_signal_mask() itself. If the wake
chain starts somewhere else, signal goes out inline and can feed back
into epoll.
Add IOU_F_TWQ_IN_WAKE, set it on the task_work add done from the three
waitqueue callbacks, and use it to force io_eventfd_signal() down the
existing call_rcu_hurry() deferral instead of signaling inline. |
| In the Linux kernel, the following vulnerability has been resolved:
net: tap: fix wrong transport_header when sending VLAN-tagged frame
In tap_get_user_xdp(), when processing a VLAN-tagged frame (e.g.
ETH_P_8021Q), skb_set_network_header() is called first to advance
network_header past the VLAN tag to the inner protocol header.
skb_probe_transport_header() is then called with skb->protocol still
set to ETH_P_8021Q, while nhoff (derived from skb_network_offset())
already points past the VLAN tag to the inner protocol header.
In __skb_flow_dissect(), proto is initialized to ETH_P_8021Q and nhoff
points past the VLAN tag. When the dissector hits case ETH_P_8021Q, it
reads a struct vlan_hdr at the current nhoff via __skb_header_pointer(),
but that offset contains the inner protocol header (e.g. an IP header).
The bytes are misinterpreted as a VLAN header, yielding a garbage
encapsulated EtherType that matches no known protocol. The dissector
returns false, so skb_probe_transport_header() never calls
skb_set_transport_header(), leaving transport_header at its uninitialized
sentinel value (~0U).
Move skb_set_network_header() to after skb_probe_transport_header(). At
the time skb_probe_transport_header() is called, network_header still
points to the VLAN header (offset ETH_HLEN), so nhoff is correct and the
flow dissector can parse the VLAN header, extract the inner EtherType,
and advance nhoff to the inner protocol header, allowing transport_header
to be set correctly. |
| In the Linux kernel, the following vulnerability has been resolved:
netfs: release readahead folios on iterator preparation failure
netfs_prepare_read_iterator() batches readahead folios in put_batch so that
the folio references can be dropped after the I/O iterator has been
prepared.
If rolling_buffer_load_from_ra() fails after earlier folios have been
batched, the function returns immediately and leaves those references held.
Release the batch before returning the error. |

| In the Linux kernel, the following vulnerability has been resolved:
tipc: avoid busy looping in tipc_exit_net()
Blamed commit introduced a busy-wait loop in tipc_exit_net()
to wait for pending UDP bearer cleanup works to complete:
while (atomic_read(&tn->wq_count))
cond_resched();
This loop can busy-wait for a long time if cond_resched() is a NOP. This
typically happens if the netns exit is executed by a high priority task,
or under kernels configured without preemption (CONFIG_PREEMPT_NONE). In
such cases, it wastes CPU cycles and can lead to soft lockups.
Fix this by replacing the busy loop with wait_var_event(), allowing the
thread to sleep properly until the work queue count reaches zero.
Accordingly, update cleanup_bearer() to use atomic_dec_and_test() and
wake_up_var() to wake up the waiter when the count drops to zero.
This uses the global wait queue hash table, avoiding the need to bloat
struct tipc_net with a wait_queue_head_t. The atomic_dec_and_test()
provides the necessary memory barrier to ensure the wakeup is not missed. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix responder UAF on IB_QP_MAX_DEST_RD_ATOMIC modify_qp
rxe_qp_from_attr() handles IB_QP_MAX_DEST_RD_ATOMIC outside the
IB_QP_STATE path, so it holds no state_lock and runs while the responder
task rxe_receiver() (recv_task on rxe_wq) is live. A modify_qp() setting
only that attribute calls free_rd_atomic_resources() then
alloc_rd_atomic_resources(), swapping qp->resp.resources[] while
rxe_prepare_res()/find_resource() walk it; free_rd_atomic_resources()
also leaves the cached pointer qp->resp.res dangling. A local
unprivileged user can race the free/realloc into a use-after-free in
rxe_receiver() (local DoS).
Drain recv_task around the swap with rxe_disable_task()/rxe_enable_task(),
as rxe_qp_reset() already does when tearing this array down, re-enabling
only after alloc_rd_atomic_resources() succeeds so the responder never
resumes against a NULL qp->resp.resources on the ENOMEM path. Also clear
qp->resp.res in free_rd_atomic_resources(), like the rxe_resp.c
completion paths.
Reproduced under KASAN; the slab-use-after-free in rxe_receiver() is gone. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: clamp route advmss to TCP_MIN_MSS
tcp_select_initial_window() assumes that callers never pass an MSS
smaller than 1, but route-derived advmss values can violate that
assumption.
A too-small explicit RTAX_ADVMSS is one way to get there, but it is not
the only one. The same divide-by-zero can also be reached through the
"default advmss" path when RTAX_ADVMSS is left at 0 and the effective
advmss is later driven down by route MTU and min_adv_mss.
Introduce a tcp_dst_advmss() helper that clamps route advmss to
TCP_MIN_MSS before TCP consumes it, and use it in the TCP paths that
derive advmss from dst metrics. This keeps the effective MSS from
dropping to zero before tcp_select_initial_window() rounds the receive
window. |
| In the Linux kernel, the following vulnerability has been resolved:
fbdev: Wrap user-invoked calls to fb_set_var() in helper
Handle fbcon during display updates in fb_set_var_from_user(). Check
with fbcon if the mode change is possible, update hardware state and
finally update fbcon. Update all callers.
Only the FBIOPUT_VSCREENINFO ioctl currently does all steps. Other
mode-changes callers in sysfs and driver code are missing fbcon-related
steps.
With the new helper, ps3fb and sh_mobile_lcdcfb no longer maintain
fbcon state themselves. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: ISO: zero the sockaddr before returning it in getname
iso_sock_getname() fills a struct sockaddr_iso in place and returns its
size without clearing it first, so bytes it does not write are copied to
user space from the kernel stack. The getsockname(2) and getpeername(2)
paths both run through do_getsockname(), which hands getname() an
uninitialized sockaddr_storage on the stack and copies back up to the
number of bytes getname() returns, so the driver has to initialize every
byte it accounts for.
Two ranges are left uninitialized:
- struct sockaddr_iso is 10 bytes but only 9 are written (family,
iso_bdaddr, iso_bdaddr_type), leaking the trailing pad byte on every
call.
- for a broadcast peer (BIS_LINK or PA_LINK) the returned length grows
by sizeof(struct sockaddr_iso_bc), but only bc_sid, bc_num_bis and
bc_bis are filled; bc_bdaddr and bc_bdaddr_type, the first 7 bytes of
that structure, are never written.
An unprivileged process can open a BTPROTO_ISO socket and reach the pad
leak with getsockname(); the broadcast leak needs an established BIS/PA
connection. l2cap and rfcomm already memset their sockaddr in getname
for the same reason; do the same here. |
