| In the Linux kernel, the following vulnerability has been resolved:
igc: Reduce TSN TX packet buffer from 7KB to 5KB per queue
The previous 7 KB per queue caused TX unit hangs under heavy
timestamping load. Reducing to 5 KB avoids these hangs and matches
the TSN recommendation in I225/I226 SW User Manual Section 7.5.4.
The 8 KB "freed" by this change is currently unused. This reduction
is not expected to impact throughput, as the i226 is PCIe-limited
for small TSN packets rather than TX-buffer-limited. |
| In the Linux kernel, the following vulnerability has been resolved:
interconnect: debugfs: initialize src_node and dst_node to empty strings
The debugfs_create_str() API assumes that the string pointer is either NULL
or points to valid kmalloc() memory. Leaving the pointer uninitialized can
cause problems.
Initialize src_node and dst_node to empty strings before creating the
debugfs entries to guarantee that reads and writes are safe. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/sysfs: cleanup attrs subdirs on context dir setup failure
When a context DAMON sysfs directory setup is failed after setup of attrs/
directory, subdirectories of attrs/ directory are not cleaned up. As a
result, DAMON sysfs interface is nearly broken until the system reboots,
and the memory for the unremoved directory is leaked.
Cleanup the directories under such failures. |
| The Zarinpal Gateway for WooCommerce plugin for WordPress is vulnerable to Improper Access Control to Payment Status Update in all versions up to and including 5.0.16. This is due to the payment callback handler 'Return_from_ZarinPal_Gateway' failing to validate that the authority token provided in the callback URL belongs to the specific order being marked as paid. This makes it possible for unauthenticated attackers to potentially mark orders as paid without proper payment by reusing a valid authority token from a different transaction of the same amount. |
| Apache NiFi 1.1.0 through 2.7.2 are missing authorization when updating configuration properties on extension components that have specific Required Permissions based on the Restricted annotation. The Restricted annotation indicates additional privileges required to add the annotated component to the flow configuration, but framework authorization did not check restricted status when updating a component previously added. The missing authorization requires a more privileged user to add a restricted component to the flow configuration, but permits a less privileged user to make property configuration changes. Apache NiFi installations that do not implement different levels of authorization for Restricted components are not subject to this vulnerability because the framework enforces write permissions as the security boundary. Upgrading to Apache NiFi 2.8.0 is the recommended mitigation. |
| Glory RBG-100 recycler systems using the ISPK-08 software component contain hard-coded operating system credentials that allow remote authentication to the underlying Linux system. Multiple local user accounts, including accounts with administrative privileges, were found to have fixed, embedded passwords. An attacker with network access to exposed services such as SSH may authenticate using these credentials and gain unauthorized access to the system. Successful exploitation allows remote access with elevated privileges and may result in full system compromise. |
| The EventPrime plugin for WordPress is vulnerable to unauthorized image file upload in all versions up to, and including, 4.2.8.4. This is due to the plugin registering the upload_file_media AJAX action as publicly accessible (nopriv-enabled) without implementing any authentication, authorization, or nonce verification despite a nonce being created. This makes it possible for unauthenticated attackers to upload image files to the WordPress uploads directory and create Media Library attachments via the ep_upload_file_media endpoint. |
| Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in EKA Software Computer Information Advertising Services Ltd. Real Estate Script V5 (With Doping Module – Store Module – New Language System) allows Cross-Site Scripting (XSS).This issue affects Real Estate Script V5 (With Doping Module – Store Module – New Language System): through 17022026.
NOTE: The vendor was contacted early about this disclosure but did not respond in any way. |
| Missing Authorization vulnerability in Smartypants SP Project & Document Manager allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects SP Project & Document Manager: from n/a through 4.70. |
| Crypt::URandom versions from 0.41 before 0.55 for Perl is vulnerable to a heap buffer overflow in the XS function crypt_urandom_getrandom().
The function does not validate that the length parameter is non-negative. If a negative value (e.g. -1) is supplied, the expression length + 1u causes an integer wraparound, resulting in a zero-byte allocation. The subsequent call to getrandom(data, length, GRND_NONBLOCK) passes the original negative value, which is implicitly converted to a large unsigned value (typically SIZE_MAX). This can result in writes beyond the allocated buffer, leading to heap memory corruption and application crash (denial of service).
In common usage, the length argument is typically hardcoded by the caller, which reduces the likelihood of attacker-controlled exploitation. Applications that pass untrusted input to this parameter may be affected. |
| Emails sent by pretix can utilize placeholders that will be filled with customer data. For example, when {name}
is used in an email template, it will be replaced with the buyer's
name for the final email. This mechanism contained a security-relevant bug:
It was possible to exfiltrate information about the pretix system through specially crafted placeholder names such as {{event.__init__.__code__.co_filename}}.
This way, an attacker with the ability to control email templates
(usually every user of the pretix backend) could retrieve sensitive
information from the system configuration, including even database
passwords or API keys. pretix does include mechanisms to prevent the usage of such
malicious placeholders, however due to a mistake in the code, they were
not fully effective for this plugin.
Out of caution, we recommend that you rotate all passwords and API keys contained in your pretix.cfg https://docs.pretix.eu/self-hosting/config/ file. |

| Concierge::Sessions versions from 0.8.1 before 0.8.5 for Perl generate insecure session ids. The generate_session_id function in Concierge::Sessions::Base defaults to using the uuidgen command to generate a UUID, with a fallback to using Perl's built-in rand function. Neither of these methods are secure, and attackers are able to guess session_ids that can grant them access to systems. Specifically,
* There is no warning when uuidgen fails. The software can be quietly using the fallback rand() function with no warnings if the command fails for any reason.
* The uuidgen command will generate a time-based UUID if the system does not have a high-quality random number source, because the call does not explicitly specify the --random option. Note that the system time is shared in HTTP responses.
* UUIDs are identifiers whose mere possession grants access, as per RFC 9562.
* The output of the built-in rand() function is predictable and unsuitable for security applications. |

*
Placeholders in subjects and plain text bodies of emails were
wrongfully evaluated twice. Therefore, if the first evaluation of a
placeholder again contains a placeholder, this second placeholder was
rendered. This allows the rendering of placeholders controlled by the
ticket buyer, and therefore the exploitation of the first issue as a
ticket buyer. Luckily, the only buyer-controlled placeholder available
in pretix by default (that is not validated in a way that prevents the
issue) is {invoice_company}, which is very unusual (but not
impossible) to be contained in an email subject template. In addition
to broadening the attack surface of the first issue, this could
theoretically also leak information about an order to one of the
attendees within that order. However, we also consider this scenario
very unlikely under typical conditions.

| The Spam protection, Anti-Spam, FireWall by CleanTalk plugin for WordPress is vulnerable to unauthorized Arbitrary Plugin Installation due to an authorization bypass via reverse DNS (PTR record) spoofing on the 'checkWithoutToken' function in all versions up to, and including, 6.71. This makes it possible for unauthenticated attackers to install and activate arbitrary plugins which can be leveraged to achieve remote code execution if another vulnerable plugin is installed and activated. Note: This is only exploitable on sites with an invalid API key. |

ice: Fix PTP NULL pointer dereference during VSI rebuild
Fix race condition where PTP periodic work runs while VSI is being
rebuilt, accessing NULL vsi->rx_rings.
The sequence was:
1. ice_ptp_prepare_for_reset() cancels PTP work
2. ice_ptp_rebuild() immediately queues PTP work
3. VSI rebuild happens AFTER ice_ptp_rebuild()
4. PTP work runs and accesses NULL vsi->rx_rings
Fix: Keep PTP work cancelled during rebuild, only queue it after
VSI rebuild completes in ice_rebuild().
Added ice_ptp_queue_work() helper function to encapsulate the logic
for queuing PTP work, ensuring it's only queued when PTP is supported
and the state is ICE_PTP_READY.

| In the Linux kernel, the following vulnerability has been resolved:
macvlan: fix error recovery in macvlan_common_newlink()
valis provided a nice repro to crash the kernel:
ip link add p1 type veth peer p2
ip link set address 00:00:00:00:00:20 dev p1
ip link set up dev p1
ip link set up dev p2
ip link add mv0 link p2 type macvlan mode source
ip link add invalid% link p2 type macvlan mode source macaddr add 00:00:00:00:00:20
ping -c1 -I p1 1.2.3.4
He also gave a very detailed analysis:
<quote valis>
The issue is triggered when a new macvlan link is created with
MACVLAN_MODE_SOURCE mode and MACVLAN_MACADDR_ADD (or
MACVLAN_MACADDR_SET) parameter, lower device already has a macvlan
port and register_netdevice() called from macvlan_common_newlink()
fails (e.g. because of the invalid link name).
In this case macvlan_hash_add_source is called from
macvlan_change_sources() / macvlan_common_newlink():
This adds a reference to vlan to the port's vlan_source_hash using
macvlan_source_entry.
vlan is a pointer to the priv data of the link that is being created.
When register_netdevice() fails, the error is returned from
macvlan_newlink() to rtnl_newlink_create():
if (ops->newlink)
err = ops->newlink(dev, ¶ms, extack);
else
err = register_netdevice(dev);
if (err < 0) {
free_netdev(dev);
goto out;
}
and free_netdev() is called, causing a kvfree() on the struct
net_device that is still referenced in the source entry attached to
the lower device's macvlan port.
Now all packets sent on the macvlan port with a matching source mac
address will trigger a use-after-free in macvlan_forward_source().
</quote valis>
With all that, my fix is to make sure we call macvlan_flush_sources()
regardless of @create value whenever "goto destroy_macvlan_port;"
path is taken.
Many thanks to valis for following up on this issue. |

rust_binder: correctly handle FDA objects of length zero
Fix a bug where an empty FDA (fd array) object with 0 fds would cause an
out-of-bounds error. The previous implementation used `skip == 0` to
mean "this is a pointer fixup", but 0 is also the correct skip length
for an empty FDA. If the FDA is at the end of the buffer, then this
results in an attempt to write 8-bytes out of bounds. This is caught and
results in an EINVAL error being returned to userspace.
The pattern of using `skip == 0` as a special value originates from the
C-implementation of Binder. As part of fixing this bug, this pattern is
replaced with a Rust enum.
I considered the alternate option of not pushing a fixup when the length
is zero, but I think it's cleaner to just get rid of the zero-is-special
stuff.
The root cause of this bug was diagnosed by Gemini CLI on first try. I
used the following prompt:
> There appears to be a bug in @drivers/android/binder/thread.rs where
> the Fixups oob bug is triggered with 316 304 316 324. This implies
> that we somehow ended up with a fixup where buffer A has a pointer to
> buffer B, but the pointer is located at an index in buffer A that is
> out of bounds. Please investigate the code to find the bug. You may
> compare with @drivers/android/binder.c that implements this correctly. |
| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (acpi_power_meter) Fix deadlocks related to acpi_power_meter_notify()
The acpi_power_meter driver's .notify() callback function,
acpi_power_meter_notify(), calls hwmon_device_unregister() under a lock
that is also acquired by callbacks in sysfs attributes of the device
being unregistered which is prone to deadlocks between sysfs access and
device removal.
Address this by moving the hwmon device removal in
acpi_power_meter_notify() outside the lock in question, but notice
that doing it alone is not sufficient because two concurrent
METER_NOTIFY_CONFIG notifications may be attempting to remove the
same device at the same time. To prevent that from happening, add a
new lock serializing the execution of the switch () statement in
acpi_power_meter_notify(). For simplicity, it is a static mutex
which should not be a problem from the performance perspective.
The new lock also allows the hwmon_device_register_with_info()
in acpi_power_meter_notify() to be called outside the inner lock
because it prevents the other notifications handled by that function
from manipulating the "resource" object while the hwmon device based
on it is being registered. The sending of ACPI netlink messages from
acpi_power_meter_notify() is serialized by the new lock too which
generally helps to ensure that the order of handling firmware
notifications is the same as the order of sending netlink messages
related to them.
In addition, notice that hwmon_device_register_with_info() may fail
in which case resource->hwmon_dev will become an error pointer,
so add checks to avoid attempting to unregister the hwmon device
pointer to by it in that case to acpi_power_meter_notify() and
acpi_power_meter_remove(). |
