Found by static analysis.
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Acquire kvm->srcu when handling KVM_SET_VCPU_EVENTS
Grab kvm->srcu when processing KVM_SET_VCPU_EVENTS, as KVM will forcibly
leave nested VMX/SVM if SMM mode is being toggled, and leaving nested VMX
reads guest memory.
Note, kvm_vcpu_ioctl_x86_set_vcpu_events() can also be called from KVM_RUN
via sync_regs(), which already holds SRCU. I.e. trying to precisely use
kvm_vcpu_srcu_read_lock() around the problematic SMM code would cause
problems. Acquiring SRCU isn't all that expensive, so for simplicity,
grab it unconditionally for KVM_SET_VCPU_EVENTS.

In the Linux kernel, the following vulnerability has been resolved:
sched: sch_cake: fix bulk flow accounting logic for host fairness
In sch_cake, we keep track of the count of active bulk flows per host,
when running in dst/src host fairness mode, which is used as the
round-robin weight when iterating through flows. The count of active
bulk flows is updated whenever a flow changes state.
This has a peculiar interaction with the hash collision handling: when a
hash collision occurs (after the set-associative hashing), the state of
the hash bucket is simply updated to match the new packet that collided,
and if host fairness is enabled, that also means assigning new per-host
state to the flow. For this reason, the bulk flow counters of the
host(s) assigned to the flow are decremented, before new state is
assigned (and the counters, which may not belong to the same host
anymore, are incremented again).
Back when this code was introduced, the host fairness mode was always
enabled, so the decrement was unconditional. When the configuration
flags were introduced the *increment* was made conditional, but
the *decrement* was not. Which of course can lead to a spurious
decrement (and associated wrap-around to U16_MAX).
AFAICT, when host fairness is disabled, the decrement and wrap-around
happens as soon as a hash collision occurs (which is not that common in
itself, due to the set-associative hashing). However, in most cases this
is harmless, as the value is only used when host fairness mode is
enabled. So in order to trigger an array overflow, sch_cake has to first
be configured with host fairness disabled, and while running in this
mode, a hash collision has to occur to cause the overflow. Then, the
qdisc has to be reconfigured to enable host fairness, which leads to the
array out-of-bounds because the wrapped-around value is retained and
used as an array index. It seems that syzbot managed to trigger this,
which is quite impressive in its own right.
This patch fixes the issue by introducing the same conditional check on
decrement as is used on increment.
The original bug predates the upstreaming of cake, but the commit listed
in the Fixes tag touched that code, meaning that this patch won't apply
before that.
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/pm: Fix negative array index read
Avoid using the negative values
for clk_idex as an index into an array pptable->DpmDescriptor.
V2: fix clk_index return check (Tim Huang)
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check gpio_id before used as array index
[WHY & HOW]
GPIO_ID_UNKNOWN (-1) is not a valid value for array index and therefore
should be checked in advance.
This fixes 5 OVERRUN issues reported by Coverity.
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check num_valid_sets before accessing reader_wm_sets[]
[WHY & HOW]
num_valid_sets needs to be checked to avoid a negative index when
accessing reader_wm_sets[num_valid_sets - 1].
This fixes an OVERRUN issue reported by Coverity.
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check msg_id before processing transcation

An arbitrary file upload vulnerability in YPay 1.2.0 allows attackers to execute arbitrary code via a ZIP archive to themePutFile in app/common/util/Upload.php (called from app/admin/controller/ypay/Home.php). The file extension of an uncompressed file is not checked.
CUPS is a standards-based, open-source printing system, and `libppd` can be used for legacy PPD file support. The `libppd` function `ppdCreatePPDFromIPP2` does not sanitize IPP attributes when creating the PPD buffer. When used in combination with other functions such as `cfGetPrinterAttributes5`, can result in user controlled input and ultimately code execution via Foomatic. This vulnerability can be part of an exploit chain leading to remote code execution (RCE), as described in CVE-2024-47176.
CUPS is a standards-based, open-source printing system, and `libcupsfilters` contains the code of the filters of the former `cups-filters` package as library functions to be used for the data format conversion tasks needed in Printer Applications. The `cfGetPrinterAttributes5` function in `libcupsfilters` does not sanitize IPP attributes returned from an IPP server. When these IPP attributes are used, for instance, to generate a PPD file, this can lead to attacker controlled data to be provided to the rest of the CUPS system.
Vault’s SSH secrets engine did not require the valid_principals list to contain a value by default. If the valid_principals and default_user fields of the SSH secrets engine configuration are not set, an SSH certificate requested by an authorized user to Vault’s SSH secrets engine could be used to authenticate as any user on the host. Fixed in Vault Community Edition 1.17.6, and in Vault Enterprise 1.17.6, 1.16.10, and 1.15.15.
Shields.io is a service for concise, consistent, and legible badges in SVG and raster format. Shields.io and users self-hosting their own instance of shields using version < `server-2024-09-25` are vulnerable to a remote execution vulnerability via the JSONPath library used by the Dynamic JSON/Toml/Yaml badges. This vulnerability would allow any user with access to make a request to a URL on the instance to the ability to execute code by crafting a malicious JSONPath expression. All users who self-host an instance are vulnerable. This problem was fixed in server-2024-09-25. Those who follow the tagged releases should update to `server-2024-09-25` or later. Those who follow the rolling tag on DockerHub, `docker pull shieldsio/shields:next` to update to the latest version. As a workaround, blocking access to the endpoints `/badge/dynamic/json`, `/badge/dynamic/toml`, and `/badge/dynamic/yaml` (e.g: via a firewall or reverse proxy in front of your instance) would prevent the exploitable endpoints from being accessed.
RSSHub is an RSS network. Prior to commit 64e00e7, RSSHub's `docker-test-cont.yml` workflow is vulnerable to Artifact Poisoning, which could have lead to a full repository takeover. Downstream users of RSSHub are not vulnerable to this issue, and commit 64e00e7 fixed the underlying issue and made the repository no longer vulnerable. The `docker-test-cont.yml` workflow gets triggered when the `PR - Docker build test` workflow completes successfully. It then collects some information about the Pull Request that triggered the triggering workflow and set some labels depending on the PR body and sender. If the PR also contains a `routes` markdown block, it will set the `TEST_CONTINUE` environment variable to `true`. The workflow then downloads and extracts an artifact uploaded by the triggering workflow which is expected to contain a single `rsshub.tar.zst` file. However, prior to commit 64e00e7, it did not validate and the contents were extracted in the root of the workspace overriding any existing files. Since the contents of the artifact were not validated, it is possible for a malicious actor to send a Pull Request which uploads, not just the `rsshub.tar.zst` compressed docker image, but also a malicious `package.json` file with a script to run arbitrary code in the context of the privileged workflow. As of commit 64e00e7, this scenario has been addressed and the RSSHub repository is no longer vulnerable.

In x86's APIC (Advanced Programmable Interrupt Controller) architecture,
error conditions are reported in a status register. Furthermore, the OS
can opt to receive an interrupt when a new error occurs.
It is possible to configure the error interrupt with an illegal vector,
which generates an error when an error interrupt is raised.
This case causes Xen to recurse through vlapic_error(). The recursion
itself is bounded; errors accumulate in the the status register and only
generate an interrupt when a new status bit becomes set.
However, the lock protecting this state in Xen will try to be taken
recursively, and deadlock.
When multiple devices share resources and one of them is to be passed
through to a guest, security of the entire system and of respective
guests individually cannot really be guaranteed without knowing
internals of any of the involved guests. Therefore such a configuration
cannot really be security-supported, yet making that explicit was so far
missing.
Resources the sharing of which is known to be problematic include, but
are not limited to
- - PCI Base Address Registers (BARs) of multiple devices mapping to the
same page (4k on x86),
- - INTx lines.
Certain PCI devices in a system might be assigned Reserved Memory
Regions (specified via Reserved Memory Region Reporting, "RMRR") for
Intel VT-d or Unity Mapping ranges for AMD-Vi. These are typically used
for platform tasks such as legacy USB emulation.
Since the precise purpose of these regions is unknown, once a device
associated with such a region is active, the mappings of these regions
need to remain continuouly accessible by the device. In the logic
establishing these mappings, error handling was flawed, resulting in
such mappings to potentially remain in place when they should have been
removed again. Respective guests would then gain access to memory
regions which they aren't supposed to have access to.
The REST API TO MiniProgram plugin for WordPress is vulnerable to SQL Injection via the 'order' parameter of the /wp-json/watch-life-net/v1/comment/getcomments REST API endpoint in all versions up to, and including, 4.7.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
The The Special Text Boxes plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 6.2.4. This is due to the plugin adding the filter add_filter('comment_text', 'do_shortcode'); which will run all shortcodes in comments. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.
The Contact Form to Any API plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Contact Form 7 form fields in all versions up to, and including, 1.2.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Integer overflow in Skia in Google Chrome prior to 129.0.6668.70 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: High)
The Thanh Toán Quét Mã QR Code Tự Động – MoMo, ViettelPay, VNPay và 40 ngân hàng Việt Nam plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 2.0.1 due to incorrect use of the wp_kses_allowed_html function, which allows the 'onclick' attribute for certain HTML elements without sufficient restriction or context validation. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Franklin Fueling Systems TS-550 EVO versions prior to 2.26.4.8967 possess a file that can be read arbitrarily that could allow an attacker obtain administrator credentials.
Rocket.Chat 6.12.0, 6.11.2, 6.10.5, 6.9.6, 6.8.6, 6.7.8, and before is vulnerable to a message forgery / impersonation issue. Attackers can abuse the UpdateOTRAck method to send ephemeral messages as if they were any other user they choose.
Proxmox Virtual Environment is an open-source server management platform for enterprise virtualization. Insufficient safeguards against malicious API response values allow authenticated attackers with 'Sys.Audit' or 'VM.Monitor' privileges to download arbitrary host files via the API.
When handling the result from a request handler before returning it to the user, the handle_api2_request function will check for the ‘download’ or ‘data’->’download’ objects inside the request handler call response object. If present, handle_api2_request will read a local file defined by this object and return it to the user.
Two endpoints were identified which can control the object returned by a request handler sufficiently that the ’download’ object is defined and user controlled. This results in arbitrary file read.
The privileges of this file read can result in full compromise of the system by various impacts such as disclosing sensitive files allowing for privileged session forgery.
A cross-site scripting (XSS) vulnerability in HelpDeskZ v2.0.2 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the Name text field of Custom Fields message box.
