| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: mmp_pdma: Fix race condition in mmp_pdma_residue()
Add proper locking in mmp_pdma_residue() to prevent use-after-free when
accessing descriptor list and descriptor contents.
The race occurs when multiple threads call tx_status() while the tasklet
on another CPU is freeing completed descriptors:
CPU 0 CPU 1
----- -----
mmp_pdma_tx_status()
mmp_pdma_residue()
-> NO LOCK held
list_for_each_entry(sw, ..)
DMA interrupt
dma_do_tasklet()
-> spin_lock(&desc_lock)
list_move(sw->node, ...)
spin_unlock(&desc_lock)
| dma_pool_free(sw) <- FREED!
-> access sw->desc <- UAF!
This issue can be reproduced when running dmatest on the same channel with
multiple threads (threads_per_chan > 1).
Fix by protecting the chain_running list iteration and descriptor access
with the chan->desc_lock spinlock. |
| 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. |
| In the Linux kernel, the following vulnerability has been resolved:
mm, shmem: prevent infinite loop on truncate race
When truncating a large swap entry, shmem_free_swap() returns 0 when the
entry's index doesn't match the given index due to lookup alignment. The
failure fallback path checks if the entry crosses the end border and
aborts when it happens, so truncate won't erase an unexpected entry or
range. But one scenario was ignored.
When `index` points to the middle of a large swap entry, and the large
swap entry doesn't go across the end border, find_get_entries() will
return that large swap entry as the first item in the batch with
`indices[0]` equal to `index`. The entry's base index will be smaller
than `indices[0]`, so shmem_free_swap() will fail and return 0 due to the
"base < index" check. The code will then call shmem_confirm_swap(), get
the order, check if it crosses the END boundary (which it doesn't), and
retry with the same index.
The next iteration will find the same entry again at the same index with
same indices, leading to an infinite loop.
Fix this by retrying with a round-down index, and abort if the index is
smaller than the truncate range. |
| An issue in Visual Studio Code Extensions Markdown Preview Enhanced v0.8.18 allows attackers to execute arbitrary code via uploading a crafted .Md file. |
| 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. |
| The RF communication protocol in the Micca KE700 car alarm system does not encrypt its data frames. An attacker with a radio interception tool (e.g., SDR) can capture the random number and counters transmitted in cleartext, which is sensitive information required for authentication. |
| A Server-Side Template Injection (SSTI) vulnerability in the Freemarker template engine of Datart v1.0.0-rc.3 allows authenticated attackers to execute arbitrary code via injecting crafted Freemarker template syntax into the SQL script field. |
| LightLLM version 1.1.0 and prior contain an unauthenticated remote code execution vulnerability in PD (prefill-decode) disaggregation mode. The PD master node exposes WebSocket endpoints that receive binary frames and pass the data directly to pickle.loads() without authentication or validation. A remote attacker who can reach the PD master can send a crafted payload to achieve arbitrary code execution. |
| A security flaw has been discovered in Intelbras VIP 3260 Z IA 2.840.00IB005.0.T. Affected by this vulnerability is an unknown functionality of the file /OutsideCmd. The manipulation results in weak password recovery. It is possible to launch the attack remotely. Attacks of this nature are highly complex. The exploitation appears to be difficult. It is recommended to upgrade the affected component. |
| An information exposure vulnerability in Datart v1.0.0-rc.3 allows authenticated attackers to access sensitive data via a custom H2 JDBC connection string. |

| Stored Cross-Site Scripting (XSS) vulnerability in Kubysoft, which is triggered through multiple parameters in the '/kForms/app' endpoint. This issue allows malicious scripts to be injected and executed persistently in the context of users accessing the affected resource. |
| 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. |
| The WP Maps – Store Locator,Google Maps,OpenStreetMap,Mapbox,Listing,Directory & Filters plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 4.8.6 via the fc_load_template function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to include and execute arbitrary .html files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .html file types can be uploaded and included. |
| The system suffers from the absence of a kernel module signature verification. If an attacker can execute commands on behalf of root user (due to additional vulnerabilities), then he/she is also able to load custom kernel modules to the kernel space and execute code in the kernel context. Such a flaw can lead to taking control over the entire system.
First identified on Nissan Leaf ZE1 manufactured in 2020. |
| Glory RBG-100 recycler systems using the ISPK-08 software component contain multiple system binaries with overly permissive file permissions. Several binaries executed by the root user are writable and executable by unprivileged local users. An attacker with local access can replace or modify these binaries to execute arbitrary commands with root privileges, enabling local privilege escalation. |
| The Kadence Blocks — Page Builder Toolkit for Gutenberg Editor plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 3.5.32. This makes it possible for authenticated attackers, with Contributor-level access and above, to perform an unauthorized action. |
| Dell Unisphere for PowerMax vApp, version(s) 9.2.4.x, contain(s) an Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to the execution of malicious HTML or JavaScript code in a victim user's web browser in the context of the vulnerable web application. Exploitation may lead to information disclosure, session theft, or client-side request forgery. |
| Missing Authentication for Critical Function vulnerability in TUBITAK BILGEM Software Technologies Research Institute Liderahenk allows Remote Code Inclusion.This issue affects Liderahenk: from 3.0.0 to 3.3.1 before 3.5.0. |
| The WhatsApp bridge component in Nanobot binds the WebSocket server to all network interfaces (0.0.0.0) on port 3001 by default and does not require authentication for incoming connections. An unauthenticated remote attacker with network access to the bridge can connect to the WebSocket server to hijack the WhatsApp session. This allows the attacker to send messages on behalf of the user, intercept all incoming messages and media in real-time, and capture authentication QR codes. |
