CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Don't call reqsk_fastopen_remove() in tcp_conn_request().
syzbot reported the splat below in tcp_conn_request(). [0]
If a listener is close()d while a TFO socket is being processed in
tcp_conn_request(), inet_csk_reqsk_queue_add() does not set reqsk->sk
and calls inet_child_forget(), which calls tcp_disconnect() for the
TFO socket.
After the cited commit, tcp_disconnect() calls reqsk_fastopen_remove(),
where reqsk_put() is called due to !reqsk->sk.
Then, reqsk_fastopen_remove() in tcp_conn_request() decrements the
last req->rsk_refcnt and frees reqsk, and __reqsk_free() at the
drop_and_free label causes the refcount underflow for the listener
and double-free of the reqsk.
Let's remove reqsk_fastopen_remove() in tcp_conn_request().
Note that other callers make sure tp->fastopen_rsk is not NULL.
[0]:
refcount_t: underflow; use-after-free.

| In the Linux kernel, the following vulnerability has been resolved:
pid: Add a judgment for ns null in pid_nr_ns
__task_pid_nr_ns
ns = task_active_pid_ns(current);
pid_nr_ns(rcu_dereference(*task_pid_ptr(task, type)), ns);
if (pid && ns->level <= pid->level) {
Sometimes null is returned for task_active_pid_ns. Then it will trigger kernel panic in pid_nr_ns.

Kernel panic - not syncing: Oops: Fatal exception in interrupt |
| Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Premmerce Premmerce User Roles premmerce-user-roles allows Stored XSS.This issue affects Premmerce User Roles: from n/a through <= 1.0.13. |
| The SVG Case Study plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file. |
| The Frontend File Manager Plugin WordPress plugin before 23.5 did not validate a path parameter and ownership of the file, allowing any authenticated users, such as subscribers to delete arbitrary files on the server |
| Insecure Permissions vulnerability in Micro-star International MSI Center Pro 2.1.37.0 allows a local attacker to execute arbitrary code via the Device_DeviceID.dat.bak file within the C:\ProgramData\MSI\One Dragon Center\Data folder |
| A Prototype Pollution issue in getsetprop 1.1.0 allows an attacker to execute arbitrary code via global.accessor. |
| Missing Authorization vulnerability in Ays Pro Survey Maker survey-maker allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Survey Maker: from n/a through <= 5.1.9.4. |
| Oxford Nanopore Technologies' MinKNOW software at or prior to version 24.11 stores authentication tokens in a file located in the system's temporary directory (/tmp) on the host machine. This directory is typically world-readable, allowing any local user or application to access the token. If the token is leaked (e.g., via malware infection or other local exploit), and remote access is enabled, it can be used to establish unauthorized remote connections to the sequencer. Remote access must be enabled for remote exploitation to succeed. This may occur either because the user has enabled remote access for legitimate operational reasons or because malware with elevated privileges (e.g., sudo access) enables it without user consent. This vulnerability can be chained with remote access capabilities to generate a developer token from a remote device. Developer tokens can be created with arbitrary expiration dates, enabling persistent access to the sequencer and bypassing standard authentication mechanisms. |
| An issue discovered in Comfast Comfast CF-616AC routers allows attackers to hijack TCP sessions which could lead to a denial of service. |
| A Buffer Copy without Checking Size of Input issue affecting the v2_sdk_service running on a set of DJI drone devices on the port 10000 could allow an attacker to cause a crash of the service through a crafted payload triggering a missing input size check in the sdk_printf function implemented in the libv2_sdk.so library used by the dji_vtwo_sdk binary implementing the service, compromising it in a term of availability and producing a denial-of-service attack. Affected models are Mavic 3 Pro until v01.01.0300, Mavic 3 until v01.00.1200, Mavic 3 Classic until v01.00.0500, Mavic 3 Enterprise until v07.01.10.03, Matrice 300 until v57.00.01.00, Matrice M30 until v07.01.0022 and Mini 3 Pro until v01.00.0620. |
| An Improper Input Validation vulnerability affecting the FTP service running on the DJI Mavic Mini 3 Pro could allow an attacker to craft a malicious packet containing a malformed path provided to the FTP SIZE command that leads to a denial-of-service attack of the FTP service itself. |
| Cognex In-Sight Explorer and In-Sight Camera Firmware expose
a proprietary protocol on TCP port 1069 to perform management operations
such as modifying system properties. The user management functionality
handles sensitive data such as registered usernames and passwords over
an unencrypted channel, allowing an adjacent attacker to intercept valid
credentials to gain access to the device. |
| Easy Cart Shopping Cart 2021 contains a non-persistent cross-site scripting vulnerability in the search module's keyword parameter. Remote attackers can inject malicious script code through the search input to compromise user sessions and manipulate application content. |
| Missing Authorization vulnerability in e-plugins Listihub listihub allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Listihub: from n/a through <= 1.0.6. |
| Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Netcad NetGIS Server allows Reflected XSS.This issue affects NetGIS Server: from 5.2.4 through 22.08.2025. |
| Ultimate POS 4.4 contains a persistent cross-site scripting vulnerability in the product name parameter that allows remote attackers to inject malicious scripts. Attackers can exploit the vulnerability through product add or edit functions to execute arbitrary JavaScript and potentially hijack user sessions. |
| WebFeed is a lightweight web feed reader extension for Firefox/Chrome. Multiple HTML injection vulnerabilities in WebFeed can lead to CSRF and UI spoofing attacks. A remote attacker can provide malicious RSS feeds and attract the victim user to visit it using WebFeed. The attacker can then inject malicious HTML into the extension page and fool the victim into sending out HTTP requests to arbitrary sites with the victim's credentials. Users are vulnerable to CSRF attacks when visiting malicious RSS feeds via WebFeed. Unwanted actions could be executed on the user's behalf on arbitrary websites. This issue has been addressed in release version 0.9.2. All users are advised to upgrade. There are no known workarounds for this vulnerability. |
| Affiliate Pro 1.7 contains multiple reflected cross-site scripting vulnerabilities in the index module's input fields. Attackers can inject malicious scripts through fullname, username, and email parameters to execute client-side attacks and manipulate browser requests. |
| Cognex In-Sight Explorer and In-Sight Camera Firmware expose
a proprietary protocol on TCP port 1069 to perform management operations
such as modifying system properties. The user management functionality
handles sensitive data such as registered usernames and passwords over
an unencrypted channel, allowing an adjacent attacker to intercept valid
credentials to gain access to the device. |
