| In the Linux kernel, the following vulnerability has been resolved:
binderfs: fix UAF write in binder_add_device
binderfs_binder_device_create() publishes the new dentry with
d_make_persistent() and then calls simple_done_creating(), which drops
the parent directory lock and the creator's dentry reference. It then
calls binder_add_device() to register the device in the global
binder_devices list.
After simple_done_creating() releases the parent directory lock, a
concurrent unlinkat() can remove the new device entry. Dropping the
creator's dentry reference can then trigger binderfs_evict_inode(),
freeing the device. binder_add_device() later accesses the freed
object, causing UAF write.

| In the Linux kernel, the following vulnerability has been resolved:
nitro_enclaves: fix use-after-free on SLOT_ALLOC failure
When ne_create_vm_ioctl() fails the SLOT_ALLOC request after
anon_inode_getfile() has succeeded, the error path calls
fput(enclave_file) and then frees ne_enclave.
In normal userspace context, fput() defers the final __fput() via
task_work. ne_enclave_release() therefore runs after ne_enclave has
already been freed and dereferences ne_enclave->slot_uid, causing a
use-after-free: KASAN: slab-use-after-free in ne_enclave_release.
The enclave has no slot allocated and is not yet linked into the
enclaves list on this error path, so ne_enclave_release() is expected
to return early when slot_uid is zero. However, reading slot_uid
already accesses the freed object.
Clear enclave_file->private_data before fput() on the error path.
ne_enclave_release() then returns immediately when private_data is
NULL, leaving the ioctl error path as the sole owner of ne_enclave.
This is safe because the file has not been fd_install()'d yet.
Tested on an AWS EC2 m5.2xlarge with CONFIG_KASAN=y. Without the
patch, the reproducer triggers a KASAN slab-use-after-free on every
SLOT_ALLOC failure. With the patch, no KASAN report is produced and
the SLOT_ALLOC error is still returned. Normal enclave creation and
teardown are unaffected. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: cdc-acm: skip URB restart in port_shutdown if disconnected
acm_port_shutdown() is called from the tty-port machinery whenever the
last user closes the port. acm_disconnect() sets acm->disconnected and
calls tty_port_tty_vhangup(), which eventually triggers port_shutdown().
At that point acm_disconnect() has already called acm_poison_urbs() and
is about to free the control and read URBs.
However, acm_port_shutdown() unconditionally calls acm_unpoison_urbs()
and, when the ALWAYS_POLL_CTRL quirk is set, immediately re-submits the
ctrlurb and all read URBs. If the concurrent acm_disconnect() then
frees those URBs and their DMA buffers while they are in-flight, the
result is a use-after-free in acm_ctrl_irq() or acm_read_bulk_callback()
accessing the freed DMA memory.
Fix by checking acm->disconnected after draining the delayed anchor and
returning early: if we are in a disconnect path the URBs must remain
poisoned and must not be resubmitted.
The early return is placed after the delayed-anchor drain loop because
that loop only cancels write-side accounting (wb->use = false and
autopm counter) and does not touch the hardware path. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: typec: anx7411 - stop the IRQ before destroying the workqueue
The IRQ is devm-managed, so it can still queue plat->work while
remove() is tearing the queue down. Disable it first. |
| In the Linux kernel, the following vulnerability has been resolved:
serial: 8250_bcm7271: fix use-after-free in brcmuart_remove()
brcmuart_handle_irq() starts priv->hrt to work around a receive-timeout
quirk of the 8250 core when hardware flow control is enabled; the timer
callback brcmuart_hrtimer_func() dereferences priv.
brcmuart_remove() cancels the hrtimer before it unregisters the port, so
a receive-timeout interrupt that arrives in between re-arms the timer.
After devm frees priv, the callback runs on freed memory.
Unregister the port before cancelling the hrtimer.
serial8250_unregister_port() shuts the port down and frees its IRQ, so
brcmuart_handle_irq() can no longer restart the timer, and the final
hrtimer_cancel() drains any timer that was armed before or during the
unregister.
This issue was found by an in-house static analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: seq: Serialize compat port-info ioctls
The native sequencer ioctl path serializes handler calls with
client->ioctl_mutex, but the translated port-info compat path invokes the
same handlers through snd_seq_kernel_client_ctl() without taking that
mutex.
This lets concurrent compat CREATE_PORT requests pass the port-count
check before any request reaches the serialized insertion. The computed
integer port index can then exceed the address field range and wrap to an
existing index. Subsequent subscriber teardown can resolve the duplicate
address to the wrong port and access a freed subscriber.
Take ioctl_mutex while dispatching converted port-info requests, matching
the native ioctl path. All translated port-info commands share this
helper, so their accesses to the client port state are serialized as
well. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Serialize SMP remote OOB data access
build_pairing_cmd() looks up remote OOB data and copies its contents
without holding hdev->lock, which serializes the list's writers. After
SMP finds an entry, a concurrent management Remove Remote OOB Data
command can unlink and free it before SMP reads its present flag or
copies its random and confirmation values. Removal can also invalidate
an entry while the lookup is still traversing the list.

Taking hdev->lock in build_pairing_cmd() would recurse for callers that
already hold it and invert the device-to-L2CAP lock order on the receive
path. Add a per-device remote_oob_lock instead, held across the SMP
lookup and copies and by the add, remove and clear helpers. Cover
initialization and in-place updates as well, so SMP cannot read partially
initialized or updated OOB values. Release the mutex on allocation
failure, preserving the existing error return.
The new critical sections acquire no device, connection or channel locks.
Writers retain their existing hdev->lock protection, which continues to
serialize the other readers without changing their locking or behavior. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlegacy: 3945: free EEPROM data on remove
il3945_pci_probe() calls il_eeprom_init(), which allocates memory for
the EEPROM data. The probe failure paths release this allocation with
il_eeprom_free(), but the remove path does not free it after a
successful probe.
As a result, the EEPROM data is leaked when the PCI device is removed.
Free the EEPROM data in il3945_pci_remove() before releasing the
mac80211 hardware structure.
This issue was found by manual code inspection. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: adc: stm32-adc: fix possible division by zero in processed channel
In case the conversion has failed or returned zero, processing *val
can lead to a division by zero. Need to check for errors, or converted
value is zero, before processing the data. In case the converted value
is zero, e.g. the Vrefint channel, this should be considered as invalid
in all cases. |
| The ACF Frontend Admin by DynamiApps WordPress plugin through 3.29.13 does not perform a capability check on one of its form-submission actions before writing submitted values into the site's global ACF options store, allowing unauthenticated visitors to overwrite site-wide option values via a public form. |
| In the Linux kernel, the following vulnerability has been resolved:
sysctl: Check range in proc_dointvec_ms_jiffies_minmax
Add the range check to do_proc_int_conv_ms_jiffies_minmax that commit
d174174c6776 ("sysctl: replace SYSCTL_INT_CONV_CUSTOM macro with

| Enterprise Architect is vulnerable to XML External Entity (XXE) injection in the XSLT Debugger feature. When a user loads a crafted XML file containing a `DOCTYPE` with an external DTD reference, the parser processes external entities, allowing an attacker to read arbitrary files from the victim's filesystem.
Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 17.1 but may also affect other versions. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: buffer: Ensure bounce buffer used for unaligned case is zeroed.
iio_push_to_buffers_with_ts_unaligned() leaks uninitialized heap memory
to userspace if the data passed in is not a multiple of 8 bytes and the
timestamp is enabled. Specify __GFP_ZERO for the devm_krealloc()
to ensure any extra space is cleared. |

| The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to DOM-Based Cross-Site Scripting via the 'redirect_url' parameter in versions up to, and including, 4.0.8 This is due to insufficient input validation in the Topbar component's back button handler. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute in the victim's browser whenever the victim accesses a page that includes the malicious payload. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: s390: Fix _gaccess_shadow_fault()
In some circumstances, it is possible that the page of nested guest
memory that is being shadowed is not present at all in the parent guest
gmap. dat_entry_walk() will not find any leaf entry and return with
-ENOENT, which will erroneously be propagated all the way to userspace.
Fix by manually calling gmap_link() on the memory of the nested guest
that is being shadowed if the mapping was not already present. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: sd_zbc: Reject disks with too many zones
sd_zbc_read_zones() computes the number of zones with 64-bit arithmetic and
stores the result in the unsigned int nr_zones field of struct
zoned_disk_info, silently truncating counts that exceed 32 bits. The
truncated count is later used to size per-zone resources, while the device
may still report more zones than fit.
Moreover, sd_zbc_report_zones() counts the reported zones with a signed int
zone_idx, which overflows past INT_MAX. Reject devices reporting more than
INT_MAX zones at scan time; such a device is not realistic for any medium
that exists today, and accepting it produces inconsistent zone bookkeeping. |
