| In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Reject oversized XDomain properties responses
tb_xdp_properties_request() allocates room for 45 data dwords in its
252-byte response buffer. The XDomain length field is six bits wide,
however, and a malicious peer can set it to 63. After the fixed response
fields are subtracted, the driver treats this as 48 data dwords.
Commit 322e93448d90 ("thunderbolt: Clamp XDomain response data copy to
allocation size") only bounds the copy against data_len. If data_len is
at least 48, memcpy() reads 192 bytes from the 180-byte res->data array,
causing a 12-byte heap out-of-bounds read. Commit 4db2bd2ed478
("thunderbolt: Limit XDomain response copy to actual frame size") limits
the earlier copy but does not constrain this header-derived length.
Reject response data lengths that exceed the allocated source buffer
before copying them into the assembled property block. |

thunderbolt: Fix NULL dereference in tb_remove_work()
There is a slight race between tb_remove_work() and tb_domain_remove()
which leads to dereferencing a NULL tb->root_switch pointer inside
tb_free_unplugged_xdomains():
Thread A Thread B
tb_remove_work()
tb_domain_remove()
mutex_lock(&tb->lock)
tb_stop()
/* doesn't cancel a running callback */
cancel_delayed_work(&tcm->remove_work)
...
tb_switch_remove(tb->root_switch)
tb->root_switch = NULL
mutex_unlock(&tb->lock)
mutex_lock(&tb->lock)
...
/* without checking ->root_switch */
tb_free_unplugged_xdomains(tb->root_switch)
mutex_unlock(&tb->lock)
Commit a8937f35cf39 ("thunderbolt: Remove XDomain from the bus without
holding tb->lock") doesn't seem right to move tb_free_unplugged_xdomains()
out of the &tb->lock section and the check for tb->root_switch, in
particular. It states:
For this reason separate removing the XDomain from the topology data
structures (where we need the lock) from unregistering the device from
the bus (where remove callbacks of the drivers are being called).
tb_free_unplugged_xdomains() belongs to the former group of functions
requiring the lock. And it also calls tb_xdomain_remove() which should
only be called with &tb->lock held.

| In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Don't access a DP tunnel after its DPRX read was canceled
tb_dp_dprx_work() checks ->dprx_canceled before it takes tb->lock so it
misses a tb_dp_dprx_stop() that could not cancel the already running
work. It then polls the DPRX capabilities and runs the callback for a
tunnel that has already been torn down while the domain is suspending or
going away.
This can be hit by cancelling the DPRX read from outside the ordered
tb->wq: During suspend tb_disconnect_and_release_dp() does just this and
with a later patch tb_stop() will do it as well. The latter in combination
with the Apple NHI where the DPRX read never completed is how I hit
this.
Check the flag with tb->lock held instead and check it again in
tb_dp_tunnel_active() because the callback runs after the lock has been
dropped again.
Also clear the flag in tb_dp_dprx_start() so that it only ever describes
the work that is currently in flight. |
| In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Tear down inactive DP tunnels when the domain is stopped
tb_stop() only tears down DMA tunnels so a DP tunnel that is still
waiting for dprx_work to complete keeps that work queued while the
routers are removed and the control channel is stopped. The work only
stops once the DPRX timeout has passed and because it requeues itself
until then the flush_workqueue() in tb_domain_remove() won't wait for its
final run. The callback then runs against a domain that is already torn
down. A reference to that domain is kept so the completion waiting for
that domain to disappear in unbind will block until the timeout is
eventually reached.
Tear down DP tunnels that are not active yet as well which also cancels
that work. Tunnels for displays that are already alive are untouched and
keep working. |
| In the Linux kernel, the following vulnerability has been resolved:
serial: ma35d1: Fix clock reference leak in ma35d1serial_probe()
of_clk_get() returns a clock with a reference that has to be released
with clk_put(). ma35d1serial_probe() never does that, so the reference
is leaked on the probe error paths and also when the port is removed.
Release it on the error paths and in ma35d1serial_remove(). |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_fs: Fix NULL pointer dereference in FUNCTIONFS_ENDPOINT_DESC
When user space sets up FunctionFS with only full-speed descriptors
(e.g., flags = FUNCTIONFS_HAS_FS_DESC) and the gadget operates at a
higher speed (such as USB_SPEED_HIGH or USB_SPEED_SUPER),
config_ep_by_speed() detects that the function lacks descriptors for
the current speed, logs a warning, and falls back to full-speed
descriptors. The endpoint is then successfully enabled via
usb_ep_enable(), and epfile->ep becomes valid.
However, when user space subsequently issues the FUNCTIONFS_ENDPOINT_DESC
ioctl to query the endpoint descriptor, ffs_epfile_ioctl() selects the
descriptor index solely based on gadget->speed:
switch (epfile->ffs->gadget->speed) {
case USB_SPEED_SUPER:
case USB_SPEED_SUPER_PLUS:
desc_idx = 2;
break;
case USB_SPEED_HIGH:
desc_idx = 1;
break;
default:
desc_idx = 0;
}
desc = epfile->ep->descs[desc_idx];
memcpy(&desc1, desc, desc->bLength);
Because user space only supplied full-speed descriptors,
epfile->ep->descs[1] is NULL. Dereferencing desc->bLength triggers an
immediate kernel NULL pointer dereference panic.
Fix this by falling back through lower speed descriptors if the current
speed descriptor was not supplied, matching the fallback logic in
config_ep_by_speed() and historical f_fs behavior. If still missing,
fall back to epfile->ep->ep->desc (the active descriptor), and return
-EINVAL safely if no valid descriptor is found. In addition, mark desc
as const to match struct usb_ep::desc and avoid discarding qualifiers. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: serial: fix port tear down use-after-free
Some drivers for multiport devices access port driver data from
completion handlers of shared URBs submitted at attach() or first open()
and stopped at disconnect() or last close(), respectively.
A simple NULL check before accessing the driver data makes sure that a
port state container has at least been allocated, but a completion
handler can still race with port tear down.
Reorder the disconnect handling so that ports are not deregistered (and
their driver data freed) until after all ports have been hung up and the
driver disconnect() callback has run so that all I/O has been stopped. |
| In the Linux kernel, the following vulnerability has been resolved:
module: fix lost error code from codetag_load_module()
If codetag_load_module() fails, err is not set to reflect the failure
and load_module() returns 0 after the module has been torn down.
Also, if the module is a livepatch, mod->klp_info allocated by
copy_module_elf() leaks on this error path. Free it via a new
livepatch_cleanup label. |
| In the Linux kernel, the following vulnerability has been resolved:
rtc: ac100: Assign .num before accessing .hws
Commit f316cdff8d67 ("clk: Annotate struct clk_hw_onecell_data with
__counted_by") annotated the hws member of 'struct clk_hw_onecell_data'
with __counted_by, which informs the bounds sanitizer (UBSAN_BOUNDS)
about the number of elements in .hws[], so that it can warn when .hws[]
is accessed out of bounds. As noted in that change, the __counted_by
member must be initialized with the number of elements before the first
array access happens, otherwise there will be a warning from each access
prior to the initialization because the number of elements is zero.
This occurs in ac100_rtc_register_clks() due to .num being assigned only
after every clkout clock has been stored in .hws[]. With
CONFIG_UBSAN_BOUNDS and a compiler that implements __counted_by (GCC
15.1+ or Clang 20.1+), this triggers an array-index-out-of-bounds report
during probe, and with CONFIG_UBSAN_TRAP the first store traps.
Initialize .num with AC100_CLKOUT_NUM, the number of elements .hws[] was
allocated with, right after the allocation. That is the value the loop
counter ends up at on the success path anyway, so the provider's
behaviour is unchanged. |
| Use after free in Windows Broadcast DVR User Service allows an authorized attacker to elevate privileges locally. |
| LobsterAI before 2026.10.16 contains a hardcoded password vulnerability that allows attackers to decrypt exported provider API keys encrypted with the constant 'lobsterai-APP'. Attackers who obtain a providers export file can derive the AES-GCM key via PBKDF2 using the embedded salt and recover every third-party AI provider API key. |
| JeecgBoot before 3.9.5 contains an sql injection vulnerability that allows authenticated attackers to bypass the SqlInjectionUtil keyword blocklist by inserting newline characters into dictionary and online report SQL fragments. Attackers can send newline-separated payloads to endpoints like /sys/dict/getDictItems for boolean or time-based blind injection, extracting database contents including administrator password hashes from sys_user. |

The last stack trace is helpful because it shows that we are cancelling
a request and looking at tb_cfg_request_cancel() what might happen is
that tb_cfg_request_work() completes right before tb_cfg_request_cancel()
starts and because of this it will call schedule_work() queueing the
same work to run again. However, it is already removed from the
request_queue and reference count is dropped so when
tb_cfg_request_work() triggers again it will access memory that is
already released.
Fix this so that we first make sure a cancelled request is not handed
away from tb_cfg_request_find() or scheduled to run. Then instead of
relying on the worker to clean up the request we will do it in
tb_cfg_request_cancel() after the work is canceled from running. Make
tb_cfg_request_dequeue() release the request only if it was actually
removed from the queue. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: serial: fix ioctl hangup race
The tty ioctls can race with hangup and end up calling into a tty driver
for a device that is already gone or powered down.
Serialise the callbacks using the tty port mutex and add the missing
checks to make sure the port has not been hung up before accessing port
driver data or hardware.
This specifically avoids dereferencing a NULL-pointer if a device is
disconnected during lengthy break signalling.
Note that TIOCGICOUNT and TIOCMIWAIT do not access port driver data or
hardware and are therefore not affected by the race. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: reject invalid 320 MHz CSA bandwidth
The HT/VHT channel definition validator can receive a 320 MHz
bandwidth indication from a received CSA frame on a non-6 GHz link.
It warns for this unsupported width but continues with an uninitialized
vht_operation.chan_width, which is then read by
ieee80211_chandef_vht_oper(). With panic_on_warn enabled, this lets a
received frame panic the kernel.
Reject the channel definition before entering the VHT operation
conversion. This preserves the existing CSA fallback while avoiding
both the warning and the uninitialized read. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: minstrel_ht: validate fixed rate index
The fixed_rate_idx debugfs file is a plain u32 attribute, so any value
can be written to it. minstrel_ht_update_stats() then copies the value
into mi->max_tp_rate[] and mi->max_prob_rate, and
minstrel_ht_set_rate() uses MI_RATE_GROUP()/MI_RATE_IDX() to index
minstrel_mcs_groups[] (42 entries) and mi->groups[].rates[] (10 entries)
with it.
Writing e.g. 65535 selects group 4095 and rate index 15, far outside
both arrays. The out-of-bounds entries are dereferenced and updated as
struct minstrel_rate_stats (retry counts, etc.), so the invalid index
corrupts adjacent kernel memory. With CONFIG_UBSAN_BOUNDS the access is
reported as an array-index-out-of-bounds in minstrel_ht_set_rate().
Only a valid group/rate pair, or U32_MAX to disable fixed rate
processing, can be used safely, so reject any other value when the
debugfs file is written.
The file is only reachable through a root-only debugfs mount, so this is
not a privilege boundary. The out-of-bounds access is still a bug that
must not be reachable through a writable debugfs attribute. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: keep fallback association elements alive
Associating to a non-transmitted MBSSID profile reads freed memory while
determining the operating channel and applying HT capabilities.
When an association response omits WMM, HT, or VHT information,
ieee80211_assoc_config_link() parses the cached BSS IEs and copies the
missing element pointers out of that fallback parse. For a
non-transmitted MBSSID profile those pointers refer to merged-profile
storage owned by the parse object, and the fallback block frees that
object at its end. The copied pointers are used afterwards to determine
the operating channel, configure bandwidth, and apply HT capabilities.
Keep the fallback parse result alive until association setup finishes.

| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: account proxy paths against the mesh path limit
Proxy-path churn can drive the interface path counter negative and let
later mesh path additions exceed MESH_MAX_MPATHS.
mesh_path_free_rcu() decrements the interface mpaths counter for entries
from both the mesh and proxy path tables, but mpp_path_add() never
reserves a slot in that counter. Removing or expiring a proxy path
therefore returns a slot that was never charged.
mesh_path_add() uses the same counter to enforce MESH_MAX_MPATHS, so once
it falls below the number of installed paths the limit no longer holds.
Reserve the shared quota before allocating a proxy path and release it on
every unsuccessful addition. Mesh and proxy paths now share one
1024-entry budget, so mpp_path_add() can return -ENOSPC at that limit. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: Update control fields on #VMEXIT if and only if VMRUN succeeded
Leave control.erap_ctl and control.clean as-is in the VMCS if VMRUN fails,
because as per AMD:
there's no explicit architectural guarantee about the behavior in the
presence of VMRUN failures. So the best thing to do would be to assume
that if VMRUN fails, the actions requested in the control fields may not
have been performed. |
