The Related Posts, Inline Related Posts, Contextual Related Posts, Related Content By PickPlugins plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including 2.0.59. This is due to missing nonce validation on a function. This makes it possible for unauthenticated attackers to inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
The Reservit Hotel WordPress plugin before 3.0 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).
The WPGet API โ Connect to any external REST API plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 2.2.10. This makes it possible for authenticated attackers, with Administrator-level access and above, to make web requests to arbitrary locations originating from the web application which can be used to query and modify information from internal services.
The VK Blocks plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.94.2.2 via the page content block. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive data including the content of private posts and pages.
The SupportCandy โ Helpdesk & Customer Support Ticket System plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.3.0 via file upload due to missing validation on a user controlled key. This makes it possible for authenticated attackers to download attachments for support tickets that don't belong to them. If an admin enables tickets for guests, this can be exploited by unauthenticated attackers.
In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: avoid garbage value in panthor_ioctl_dev_query()
'priorities_info' is uninitialized, and the uninitialized value is copied
to user object when calling PANTHOR_UOBJ_SET(). Using memset to initialize
'priorities_info' to avoid this garbage value problem.
In the Linux kernel, the following vulnerability has been resolved:
amdkfd: properly free gang_ctx_bo when failed to init user queue
The destructor of a gtt bo is declared as
void amdgpu_amdkfd_free_gtt_mem(struct amdgpu_device *adev, void **mem_obj);
Which takes void** as the second parameter.
GCC allows passing void* to the function because void* can be implicitly
casted to any other types, so it can pass compiling.
However, passing this void* parameter into the function's
execution process(which expects void** and dereferencing void**)
will result in errors.

In the Linux kernel, the following vulnerability has been resolved:
thermal/netlink: Prevent userspace segmentation fault by adjusting UAPI header
The intel-lpmd tool [1], which uses the THERMAL_GENL_ATTR_CPU_CAPABILITY
attribute to receive HFI events from kernel space, encounters a
segmentation fault after commit 1773572863c4 ("thermal: netlink: Add the
commands and the events for the thresholds").
The issue arises because the THERMAL_GENL_ATTR_CPU_CAPABILITY raw value
was changed while intel_lpmd still uses the old value.
Although intel_lpmd can be updated to check the THERMAL_GENL_VERSION and
use the appropriate THERMAL_GENL_ATTR_CPU_CAPABILITY value, the commit
itself is questionable.
The commit introduced a new element in the middle of enum thermal_genl_attr,
which affects many existing attributes and introduces potential risks
and unnecessary maintenance burdens for userspace thermal netlink event
users.
Solve the issue by moving the newly introduced
THERMAL_GENL_ATTR_TZ_PREV_TEMP attribute to the end of the
enum thermal_genl_attr. This ensures that all existing thermal generic
netlink attributes remain unaffected.

In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Load DR6 with guest value only before entering .vcpu_run() loop
Move the conditional loading of hardware DR6 with the guest's DR6 value
out of the core .vcpu_run() loop to fix a bug where KVM can load hardware
with a stale vcpu->arch.dr6.
When the guest accesses a DR and host userspace isn't debugging the guest,
KVM disables DR interception and loads the guest's values into hardware on
VM-Enter and saves them on VM-Exit. This allows the guest to access DRs
at will, e.g. so that a sequence of DR accesses to configure a breakpoint
only generates one VM-Exit.
For DR0-DR3, the logic/behavior is identical between VMX and SVM, and also
identical between KVM_DEBUGREG_BP_ENABLED (userspace debugging the guest)
and KVM_DEBUGREG_WONT_EXIT (guest using DRs), and so KVM handles loading
DR0-DR3 in common code, _outside_ of the core kvm_x86_ops.vcpu_run() loop.
But for DR6, the guest's value doesn't need to be loaded into hardware for
KVM_DEBUGREG_BP_ENABLED, and SVM provides a dedicated VMCB field whereas
VMX requires software to manually load the guest value, and so loading the
guest's value into DR6 is handled by {svm,vmx}_vcpu_run(), i.e. is done
_inside_ the core run loop.
Unfortunately, saving the guest values on VM-Exit is initiated by common
x86, again outside of the core run loop. If the guest modifies DR6 (in
hardware, when DR interception is disabled), and then the next VM-Exit is
a fastpath VM-Exit, KVM will reload hardware DR6 with vcpu->arch.dr6 and
clobber the guest's actual value.
The bug shows up primarily with nested VMX because KVM handles the VMX
preemption timer in the fastpath, and the window between hardware DR6
being modified (in guest context) and DR6 being read by guest software is
orders of magnitude larger in a nested setup. E.g. in non-nested, the
VMX preemption timer would need to fire precisely between #DB injection
and the #DB handler's read of DR6, whereas with a KVM-on-KVM setup, the
window where hardware DR6 is "dirty" extends all the way from L1 writing
DR6 to VMRESUME (in L1).

usb: gadget: f_midi: fix MIDI Streaming descriptor lengths
While the MIDI jacks are configured correctly, and the MIDIStreaming
endpoint descriptors are filled with the correct information,
bNumEmbMIDIJack and bLength are set incorrectly in these descriptors.
This does not matter when the numbers of in and out ports are equal, but
when they differ the host will receive broken descriptors with
uninitialized stack memory leaking into the descriptor for whichever
value is smaller.
The precise meaning of "in" and "out" in the port counts is not clearly
defined and can be confusing. But elsewhere the driver consistently
uses this to match the USB meaning of IN and OUT viewed from the host,
so that "in" ports send data to the host and "out" ports receive data
from it.

In the Linux kernel, the following vulnerability has been resolved:
seccomp: passthrough uretprobe systemcall without filtering
When attaching uretprobes to processes running inside docker, the attached
process is segfaulted when encountering the retprobe.
The reason is that now that uretprobe is a system call the default seccomp
filters in docker block it as they only allow a specific set of known
syscalls. This is true for other userspace applications which use seccomp
to control their syscall surface.
Since uretprobe is a "kernel implementation detail" system call which is
not used by userspace application code directly, it is impractical and
there's very little point in forcing all userspace applications to
explicitly allow it in order to avoid crashing tracked processes.
Pass this systemcall through seccomp without depending on configuration.
Note: uretprobe is currently only x86_64 and isn't expected to ever be
supported in i386.

domain_remove_dev_pasid can't find the `pasid`. In case it nevertheless
happens we must avoid using a NULL pointer.
In the Linux kernel, the following vulnerability has been resolved:
block: don't revert iter for -EIOCBQUEUED
blkdev_read_iter() has a few odd checks, like gating the position and
count adjustment on whether or not the result is bigger-than-or-equal to
zero (where bigger than makes more sense), and not checking the return
value of blkdev_direct_IO() before doing an iov_iter_revert(). The
latter can lead to attempting to revert with a negative value, which
when passed to iov_iter_revert() as an unsigned value will lead to
throwing a WARN_ON() because unroll is bigger than MAX_RW_COUNT.
Be sane and don't revert for -EIOCBQUEUED, like what is done in other
spots.
In the Linux kernel, the following vulnerability has been resolved:
PCI: Avoid putting some root ports into D3 on TUXEDO Sirius Gen1
commit 9d26d3a8f1b0 ("PCI: Put PCIe ports into D3 during suspend") sets the
policy that all PCIe ports are allowed to use D3. When the system is
suspended if the port is not power manageable by the platform and won't be
used for wakeup via a PME this sets up the policy for these ports to go
into D3hot.
This policy generally makes sense from an OSPM perspective but it leads to
problems with wakeup from suspend on the TUXEDO Sirius 16 Gen 1 with a
specific old BIOS. This manifests as a system hang.
On the affected Device + BIOS combination, add a quirk for the root port of
the problematic controller to ensure that these root ports are not put into
D3hot at suspend.
This patch is based on
https://lore.kernel.org/linux-pci/20230708214457.1229-2-mario.limonciello@amd.com
but with the added condition both in the documentation and in the code to
apply only to the TUXEDO Sirius 16 Gen 1 with a specific old BIOS and only
the affected root ports.

ServiceNow has addressed an authorization bypass vulnerability that was identified in the Washington release of the Now Platform. This vulnerability, if exploited, potentially could enable an authenticated user to access unauthorized data stored within the Now Platform that the user otherwise would not be entitled to access.
This issue is addressed in the listed patches and family release, which have been made available to hosted and self-hosted customers, as well as partners.
In the Linux kernel, the following vulnerability has been resolved:
drm/v3d: Stop active perfmon if it is being destroyed
If the active performance monitor (`v3d->active_perfmon`) is being
destroyed, stop it first. Currently, the active perfmon is not
stopped during destruction, leaving the `v3d->active_perfmon` pointer
stale. This can lead to undefined behavior and instability.
This patch ensures that the active perfmon is stopped before being
destroyed, aligning with the behavior introduced in commit
7d1fd3638ee3 ("drm/v3d: Stop the active perfmon before being destroyed").
In the Linux kernel, the following vulnerability has been resolved:
tomoyo: don't emit warning in tomoyo_write_control()
syzbot is reporting too large allocation warning at tomoyo_write_control(),
for one can write a very very long line without new line character. To fix
this warning, I use __GFP_NOWARN rather than checking for KMALLOC_MAX_SIZE,
for practically a valid line should be always shorter than 32KB where the
"too small to fail" memory-allocation rule applies.
One might try to write a valid line that is longer than 32KB, but such
request will likely fail with -ENOMEM. Therefore, I feel that separately
returning -EINVAL when a line is longer than KMALLOC_MAX_SIZE is redundant.
There is no need to distinguish over-32KB and over-KMALLOC_MAX_SIZE.
In the Linux kernel, the following vulnerability has been resolved:
firmware: qcom: scm: Fix missing read barrier in qcom_scm_get_tzmem_pool()
Commit 2e4955167ec5 ("firmware: qcom: scm: Fix __scm and waitq
completion variable initialization") introduced a write barrier in probe
function to store global '__scm' variable. We all known barriers are
paired (see memory-barriers.txt: "Note that write barriers should
normally be paired with read or address-dependency barriers"), therefore
accessing it from concurrent contexts requires read barrier. Previous
commit added such barrier in qcom_scm_is_available(), so let's use that
directly.
Lack of this read barrier can result in fetching stale '__scm' variable
value, NULL, and dereferencing it.
Note that barrier in qcom_scm_is_available() satisfies here the control
dependency.

In the Linux kernel, the following vulnerability has been resolved:
media: uvcvideo: Fix crash during unbind if gpio unit is in use
We used the wrong device for the device managed functions. We used the
usb device, when we should be using the interface device.
If we unbind the driver from the usb interface, the cleanup functions
are never called. In our case, the IRQ is never disabled.
If an IRQ is triggered, it will try to access memory sections that are
already free, causing an OOPS.
We cannot use the function devm_request_threaded_irq here. The devm_*
clean functions may be called after the main structure is released by
uvc_delete.
Luckily this bug has small impact, as it is only affected by devices
with gpio units and the user has to unbind the device, a disconnect will
not trigger this error.
