CVSS v3.1 |
| The Create plugin for WordPress is vulnerable to generic SQL Injection via the 'order' parameter in all versions up to, and including, 2.5.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with author-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The vulnerable advanced-filter SQL branch is only entered when at least one of the following parameters is present in the request: linked_posts, created_after, created_before, missing_fields, post_id, a comma-separated type value, or exclude_type. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: do not attach hif2 WED when the main WED attach failed
If the WED attach for the primary PCIe function fails, the probe path
still attached wed_hif2 for the secondary function, leaving the device
in an inconsistent half-WED configuration that crashes later. The hif2
call also re-enabled hwrro_mode, which the failed primary attach had
just turned off.
Skip the hif2 WED setup when the primary WED device is not active. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: fix double hif2 init on the non-WED path
mt7915_pci_init_hif2() was called unconditionally and again inside the
WED-inactive branch. The helper increments the global hif_idx, writes the
PCIe RECOG_ID register and takes a get_device() reference via
mt7915_pci_get_hif2(), while removal only drops one reference. On non-WED
dual-hif hardware this double-incremented hif_idx, wrote RECOG_ID twice and
leaked a device reference. Only the call inside the WED-inactive branch is
correct; drop the unconditional one. hif2 is already initialised to NULL. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix leak in ath11k_service_ready_ext_event()
Currently, during ath11k_service_ready_ext_event() processing,
svc_rdy_ext.mac_phy_caps can be allocated during TLV parsing. This is a
temporary allocation that is freed on the success path, but not on the
error path. If parsing succeeds far enough to allocate mac_phy_caps and
then fails on a later TLV, the allocation leaks. So free the allocation
on the error path.
Compile tested only. |
| In the Linux kernel, the following vulnerability has been resolved:
ACPI: processor: Unregister cpufreq notifier on init failure
acpi_processor_driver_init() registers the cpufreq policy notifier before
registering the ACPI processor driver and setting up CPU hotplug state.
If driver_register() or cpuhp_setup_state() fails, the error path only
unregisters the ACPI processor driver and the idle driver. The cpufreq
notifier remains registered even though initialization failed.
Mirror the module exit path on the init failure path and unregister the
cpufreq notifier when it has been registered. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: hold dev->mt76.mutex while disabling tx worker in SER
mt7996_mac_reset_work() parked the tx worker and disabled the RX/TX NAPIs
before taking dev->mt76.mutex. mt76_worker_disable()/_enable() are plain
kthread park/unpark, not refcounted, and __mt76_set_channel() toggles the
same worker and the MT76_RESET bit under the mutex. An L1 SER racing a
channel switch could therefore have the worker unparked and MT76_RESET
cleared while the reset path resets the DMA rings, corrupting descriptors
or tokens. Take the mutex before disabling the worker, as mt7915 does. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: fix out-of-bounds access in mmio copy helpers
mt76_mmio_write_copy() and mt76_mmio_read_copy() iterate up to
ALIGN(len, 4), so a length that is not a multiple of four reads past the
source buffer (write_copy) or writes past the destination (read_copy).
Copy the aligned body in the loop and handle the remaining tail through a
4-byte bounce buffer, keeping the register access width unchanged. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: avoid nss underflow in mt7915_mcu_get_sta_nss
If a peer's VHT/HE MCS map has no supported spatial stream (all fields
0x3), the loop exits with nss == 0 and the function returned (u8)-1 (255),
which was then written into the firmware sta_rec_bf beamforming fields.
Clamp the result to 0. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: clear wcid mask under mutex after RCU pointer clear
mt7915_remove_interface() cleared the wcid mask bit with no lock held and
before clearing the RCU wcid pointer. The mask is a non-atomic RMW shared
with the allocators, which all run under dev->mt76.mutex; on DBDC the two
wiphys share one mt76_dev, so this raced add_interface/sta_add on the
other band and could leak or double-hand-out a wcid. Clearing the bit
before the RCU pointer also let a concurrent allocation reuse the index
and publish its wcid, which the subsequent NULL assignment then wiped.
Move the clear into the existing mutex section, after the RCU pointer is
cleared. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: validate RX band_idx before dereferencing phys[]
band_idx comes from a 2-bit descriptor field (0-3) and was used directly
to index dev->mt76.phys[] (size __MT_MAX_BAND == 3) and dereference the
result. A corrupt or reserved descriptor value could index out of bounds
or hit a NULL phy on parts with fewer bands. Reject invalid band indices,
mirroring mt7996_rx_get_wcid(). |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix potential UAF in bpf_netns_link_update_prog
In bpf_netns_link_update_prog, the checks for old_prog and prog type
are currently performed locklessly before acquiring netns_bpf_mutex.
This creates a race condition that can lead to a UAF issue.
If two threads concurrently execute BPF_LINK_UPDATE on the same netns
link, the following execution path can trigger a UAF:
CPU0 CPU1
bpf_netns_link_update_prog
if (old_prog && old_prog != link->prog)
return -EPERM;
bpf_netns_link_update_prog
if (old_prog && old_prog != link->prog)
...
old_prog = xchg(&link->prog, new_prog);
bpf_prog_put(old_prog);
if (new_prog->type != link->prog->type) <-- trigger UAF
Fix this by moving the old_prog and prog->type checks inside the
netns_bpf_mutex critical section. Meanwhile, use guard() to simplify
lock management and avoid all the goto jumping. |
| In the Linux kernel, the following vulnerability has been resolved:
platform/chrome: cros_ec_debugfs: Unregister panic notifier
cros_ec_debugfs_probe() registers notifier_panic with the EC panic
notifier chain. The remove path tears down debugfs and the console log,
but leaves the notifier registered. A later panic notification can call
back into the removed instance and queue work that accesses released
data.
Unregister the panic notifier before tearing down the debugfs and
console log state.
This issue was found by a static analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt792x: Fix memory leak in SDIO TX path
When tx_prepare_skb() returns an error in the SDIO TX path, the
skb is not freed, leading to a memory leak. This can occur when
zero-length frames (such as WNM NULL frames) are dropped to prevent
potential hardware TX hangs.
Fix this by properly releasing the skb with ieee80211_tx_status_ext()
when tx_prepare_skb() fails. |
| In the Linux kernel, the following vulnerability has been resolved:
misc: sgi-gru: remove interrupt-context page-table walks
The GRU TLB miss handler walks a process's page tables without holding
page-table locks or a reference to the mapped page. It also uses a kernel
page-table accessor on user page tables and supports only PMD-level large
mappings on x86-64.
Remove the direct walker. Send interrupt faults directly to user polling
mode so the existing call-OS fallback retries them in process context.
Remove the mmap-lock failure statistic that can no longer be incremented. |
| In the Linux kernel, the following vulnerability has been resolved:
md/raid1: create serial pool adding rdev to array with serialize_policy=1
The following bug has been observed with kernel 7.1.3 after adding a new
rdev to an existing RAID1 array with serialize_policy enabled:
Oops: 0002 [#1]
CPU: 0 UID: 0 PID: 19639 Comm: ext4lazyinit Not tainted 7.1.3-1-default
RIP: _raw_spin_lock_irqsave+0x27/0x50
CR2: 0000000000004960
Call Trace:
wait_for_serialization+0xb9/0x260 [raid1]
raid1_make_request+0x762/0xaff [raid1]
md_handle_request+0x1c9/0x2e0 [md_mod]
The raid1.c code calls wait_for_serialization() if the MD_SERIALIZE_POLICY
is set, and wait_for_serialization assumes that rdev->serial is
initialized. Normally this will be the case for arrays that have
the serialize_policy sysfs attribute set to 1.
But when a new rdev is added to an existing array in bind_rdev_to_array(),
the condition at mddev_create_serial_pool() causes creation of rdev->serial
to be skipped. Fix it. |
| In the Linux kernel, the following vulnerability has been resolved:
lib/test_hmm: fail dmirror_fault() when the mirrored mm is gone
dmirror_fault() is called from the dmirror_read() and dmirror_write()
retry loops after dmirror_do_read() or dmirror_do_write() finds a missing
device page table entry.
If the mirrored mm has already exited, mmget_not_zero() fails. The
current code returns 0 in that case, which tells the caller that faulting
succeeded even though no page was faulted and no device page table entry
was installed. The caller then retries the same address, hits -ENOENT
again, and can loop forever without making progress.
Return -EFAULT instead, so the ioctl fails when the mirrored mm is no
longer faultable. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: davinci: switch to managed controller allocation
The controller is allocated with the non-managed spi_alloc_host() while
the interrupt is registered with devm_request_threaded_irq(). During
removal, spi_bitbang_stop() only unregisters the controller; the
subsequent spi_controller_put() then frees the controller together with
its embedded davinci_spi devdata, which is the IRQ handler's dev_id.
The devm_request_threaded_irq() release action (free_irq()), which
drains the handler, does not run until after .remove() returns. A late
or latched interrupt can therefore reach davinci_spi_irq() and
dereference already-freed memory.
Switch to devm_spi_alloc_host() so that the devres LIFO order releases
the controller only after free_irq() has drained the handler, and drop
the now-redundant spi_controller_put() from .remove(). The probe error
path is simplified to direct returns.
The clock is acquired with devm_clk_get_enabled(), which is registered
after the IRQ and thus released before it by the devres LIFO order.
Drain the interrupt explicitly with devm_free_irq() before disabling the
controller so that a late interrupt cannot access the registers of a
clock-gated controller.
This issue was found by an in-house static analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
nvmet: fix return status of RMI log page on allocation failure
nvmet_execute_get_log_page_rmi() leaves 'status' holding NVME_SC_SUCCESS
(set by the successful nvmet_req_find_ns() call) when the kzalloc() for
the log buffer fails. It then jumps to the out label and completes the
request with a success status, so the host is told the command succeeded
while no data was transferred.
Initialize 'status' to NVME_SC_INTERNAL, matching the smart log handler,
so an allocation failure is reported as an internal error. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/tegra241-cmdqv: Fix VINTF0 leak on the init-failure path
tegra241_cmdqv_init_structures() allocates VINTF0 with kzalloc_obj(), inits
it, and preallocates its logical VCMDQs. Two of its error paths leak.
When tegra241_cmdqv_init_vintf() fails it returns before VINTF0 reaches the
cmdqv->vintfs[] array, so the devres unwind on probe failure cannot reach
it; free it directly there.
A later VCMDQ preallocation failure instead leaves VINTF0 published, and so
this time the unwind does reach tegra241_cmdqv_remove_vintf(), which then
frees it from vintf->hyp_own. But tegra241_vintf_hw_init() sets that flag
only afterward, from a HW read-back, so the still-uninited VINTF0 reads as
guest-owned and leaks, with mutex_destroy() and ida_destroy() run on fields
it never set up.
Decide ownership from vintf->idx instead, the index assigned when its id is
allocated: idx 0 is the kernel-owned VINTF0, while idx >= 1 marks a guest
VINTF. So the in-kernel free decision in tegra241_cmdqv_remove_vintf() and
tegra241_vintf_free_lvcmdq() now keys on idx too, and hyp_own stays a pure
HW-readback state. |
| In the Linux kernel, the following vulnerability has been resolved:
remoteproc: Prevent crash handling to race with rproc_del()
There's no synchronization between rproc_crash_handler_work() and
rproc_del(), as such it's possible for a driver to be removed while
crash-handler work is scheduled, or even executing - resulting in
use-after-free issues.
To avoid this the scheduled work need to be cancelled and synchronized
against before the removal proceeds.
In order to ensure that this doesn't race with the reporting, and
thereby scheduling new work, a "deleting" flag is introduced. This is
similar to the RPROC_DELETE state that was introduced to ensure that
"start" didn't race with rproc_del(), but the existing mechanism can not
be used as it's valid to call rproc_report_crash() in atomic context -
and the "state" is protected by a mutex.
In the event that work is cancelled the pm_stay_awake() is left
unbalanced and need to be unrolled.
The blocking and cancelling of crash-handler work prior to the actual
rproc_shutdown() call does have the explicit side-effect that crashes
resulting from the shutdown process will not enter the crash-handling
path, and as such will not generate devcoredumps etc. Due to the
existing mutual exclusion between these code paths there's no concrete
reduction in functionality, but further work would be needed to handle
this case. |
