| In the Linux kernel, the following vulnerability has been resolved:
NFSD: Defer sub-object cleanup in export put callbacks
svc_export_put() calls path_put() and auth_domain_put() immediately
when the last reference drops, before the RCU grace period. RCU
readers in e_show() and c_show() access both ex_path (via
seq_path/d_path) and ex_client->name (via seq_escape) without
holding a reference. If cache_clean removes the entry and drops the
last reference concurrently, the sub-objects are freed while still
in use, producing a NULL pointer dereference in d_path.
Commit 2530766492ec ("nfsd: fix UAF when access ex_uuid or
ex_stats") moved kfree of ex_uuid and ex_stats into the
call_rcu callback, but left path_put() and auth_domain_put() running
before the grace period because both may sleep and call_rcu
callbacks execute in softirq context.
Replace call_rcu/kfree_rcu with queue_rcu_work(), which defers the
callback until after the RCU grace period and executes it in process
context where sleeping is permitted. This allows path_put() and
auth_domain_put() to be moved into the deferred callback alongside
the other resource releases. Apply the same fix to expkey_put(),
which has the identical pattern with ek_path and ek_client.
A dedicated workqueue scopes the shutdown drain to only NFSD
export release work items; flushing the shared
system_unbound_wq would stall on unrelated work from other
subsystems. nfsd_export_shutdown() uses rcu_barrier() followed
by flush_workqueue() to ensure all deferred release callbacks
complete before the export caches are destroyed.

| Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.8, apps that register an asynchronous session.setPermissionRequestHandler() may be vulnerable to a use-after-free when handling fullscreen, pointer-lock, or keyboard-lock permission requests. If the requesting frame navigates or the window closes while the permission handler is pending, invoking the stored callback dereferences freed memory, which may lead to a crash or memory corruption. Apps that do not set a permission request handler, or whose handler responds synchronously, are not affected. This issue has been patched in versions 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.8. |
| Hirschmann Industrial HiVision version 08.1.03 prior to 08.1.04 and 08.2.00 contains a vulnerability in the execution of user-configured external applications that allows a local attacker to execute arbitrary binaries. Due to insufficient path sanitization, an attacker can place a malicious binary in the execution path of a configured external application, causing it to be executed instead of the intended application. This can result in execution with elevated privileges depending on the context of the external application. |
| The wpForo Forum plugin for WordPress is vulnerable to arbitrary file deletion in all versions up to, and including, 2.4.16. This is due to a missing file name/path validation against path traversal sequences. This makes it possible for authenticated attackers, with subscriber level access and above, to delete arbitrary files on the server by embedding a crafted path traversal string in a forum post body and then deleting the post. |
| Termite 3.4 contains a buffer overflow vulnerability in the User interface language settings field that allows local attackers to cause a denial of service by supplying an excessively long string. Attackers can paste a 2000-byte payload into the Settings User interface language field to crash the application. |
| Hirschmann HiLCOS devices OpenBAT, WLC, BAT300, BAT54 prior to 8.80 and OpenBAT prior to 9.10 are shipped with identical default SSH and SSL keys that cannot be changed, allowing unauthenticated remote attackers to decrypt or intercept encrypted management communications. Attackers can perform man-in-the-middle attacks, impersonate devices, and expose sensitive information by leveraging the shared default cryptographic keys across multiple devices. |
| NetSchedScan 1.0 contains a buffer overflow vulnerability in the scan Hostname/IP field that allows local attackers to crash the application by supplying an oversized input string. Attackers can paste a crafted payload containing 388 bytes of data followed by 4 bytes of EIP overwrite into the Hostname/IP field to trigger a denial of service condition. |
| Snews CMS 1.7 contains an unrestricted file upload vulnerability that allows unauthenticated attackers to upload arbitrary files including PHP executables to the snews_files directory. Attackers can upload malicious PHP files through the multipart form-data upload endpoint and execute them by accessing the uploaded file path to achieve remote code execution. |
| Redaxo CMS 5.2 contains a cross-site request forgery vulnerability that allows unauthenticated attackers to create administrative user accounts by tricking authenticated administrators into visiting malicious pages. Attackers can craft HTML forms targeting the users endpoint with hidden fields containing admin credentials and account parameters to add new administrator accounts without user consent. |
| Nodcms contains a cross-site request forgery vulnerability that allows attackers to perform unauthorized administrative actions by crafting malicious forms. Attackers can trick authenticated administrators into submitting requests to admin/user_manipulate and admin/settings/generall endpoints to create users or modify application settings without explicit consent. |
| IObit Advanced SystemCare 10.0.2 contains an unquoted service path vulnerability in the AdvancedSystemCareService10 service that allows local attackers to escalate privileges. Attackers can place a malicious executable in the service path and trigger privilege escalation when the service restarts or the system reboots, executing code with LocalSystem privileges. |
| NETGATE Registry Cleaner build 16.0.205 contains an unquoted service path vulnerability in the NGRegClnSrv service that allows local attackers to escalate privileges by exploiting the service binary path. Attackers can place a malicious executable in the unquoted path and trigger service restart or system reboot to execute code with LocalSystem privileges. |
| Netgate AMITI Antivirus build 23.0.305 contains an unquoted service path vulnerability in the AmitiAvSrv and AmitiAntivirusHealth services that allows local attackers to escalate privileges. Attackers can place a malicious executable in the unquoted service path and trigger service restart or system reboot to execute code with LocalSystem privileges. |
| IObit Malware Fighter 4.3.1 contains an unquoted service path vulnerability in the IMFservice and LiveUpdateSvc services that allows local attackers to escalate privileges. Attackers can insert a malicious executable file in the unquoted service path and trigger privilege escalation when the service restarts or the system reboots, executing code with LocalSystem privileges. |
| Hotspot Shield 6.0.3 contains an unquoted service path vulnerability in the hshld service binary that allows local attackers to escalate privileges by injecting malicious executables. Attackers can place executable files in the service path and upon service restart or system reboot, the malicious code executes with LocalSystem privileges. |
| sheed AntiVirus 2.3 contains an unquoted service path vulnerability in the ShavProt service that allows local attackers to escalate privileges by exploiting the service binary path. Attackers can insert a malicious executable in the unquoted path and trigger service restart or system reboot to execute code with LocalSystem privileges. |
| Hirschmann HiLCOS products OpenBAT, BAT450, WLC, BAT867 contains a firewall filtering vulnerability that fails to correctly filter IPv4 multicast and broadcast traffic when management IP address filtering is disabled, allowing configured filter rules to be bypassed. Attackers with network access can inject or observe multicast and broadcast packets that should have been blocked by the firewall. |
| GarrettCom Magnum 6K and 10K managed switches contain an authentication bypass vulnerability that allows unauthenticated attackers to gain unauthorized access by exploiting a hardcoded string in the authentication mechanism. Attackers can bypass login controls to access administrative functions and sensitive switch configuration without valid credentials. |
| ProSoft Technology ICX35-HWC version 1.3 and prior cellular gateways contain an authentication bypass vulnerability in the web user interface that allows unauthenticated attackers to gain access to administrative functions without valid credentials. Attackers can bypass the authentication mechanism in affected firmware versions to obtain full administrative access to device configuration and settings. |
| ProSoft Technology ICX35-HWC versions 1.3 and prior cellular gateways contain an input validation vulnerability in the web user interface that allows remote attackers to inject and execute system commands by submitting malicious input through unvalidated fields. Attackers can exploit this vulnerability to gain root privileges and execute arbitrary commands on the device through the accessible web interface. |
