*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ksmbd: fix recursive locking in RPC handle list access<br /> <br /> Since commit 305853cce3794 ("ksmbd: Fix race condition in RPC handle list<br /> access"), ksmbd_session_rpc_method() attempts to lock sess-&gt;rpc_lock.<br /> <br /> This causes hung connections / tasks when a client attempts to open<br /> a named pipe.

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/xe: Don&amp;#39;t allow evicting of BOs in same VM in array of VM binds<br /> <br /> An array of VM binds can potentially evict other buffer objects (BOs)<br /> within the same VM under certain conditions, which may lead to NULL<br /> pointer dereferences later in the bind pipeline. To prevent this, clear<br /> the allow_res_evict flag in the xe_bo_validate call.<br /> <br /> v2:<br /> - Invert polarity of no_res_evict (Thomas)<br /> - Add comment in code explaining issue (Thomas)<br /> <br /> (cherry picked from commit 8b9ba8d6d95fe75fed6b0480bb03da4b321bea08)

*** Pendiente de traducción *** A vulnerability exists in Progress Flowmon versions prior 12.5.6 where certain system configuration files have incorrect file permissions, allowing a user with access to the default flowmon system user account used for SSH access to potentially escalate privileges to root during service initialization.

*** Pendiente de traducción *** The AppPresser – Mobile App Framework plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the &amp;#39;myappp_verify&amp;#39; function in all versions up to, and including, 4.5.0. This makes it possible for unauthenticated attackers to extract sensitive data including plugin and theme names and version numbers, which can be used to facilitate targeted attacks against outdated or vulnerable components.

*** Pendiente de traducción *** A flaw was found in the X.Org X server and Xwayland when processing X11 Present extension notifications. Improper error handling during notification creation can leave dangling pointers that lead to a use-after-free condition. This can cause memory corruption or a crash, potentially allowing an attacker to execute arbitrary code or cause a denial of service.

*** Pendiente de traducción *** A flaw was discovered in the X.Org X server’s X Keyboard (Xkb) extension when handling client resource cleanup. The software frees certain data structures without properly detaching related resources, leading to a use-after-free condition. This can cause memory corruption or a crash when affected clients disconnect.

*** Pendiente de traducción *** The NS Maintenance Mode for WP WordPress plugin through 1.3.1 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).

*** Pendiente de traducción *** The Site Checkup Debug AI Troubleshooting with Wizard and Tips for Each Issue plugin for WordPress is vulnerable to log file poisoning in all versions up to, and including, 1.47. This makes it possible for unauthenticated attackers to insert arbitrary content into log files, and potentially cause denial of service via disk space exhaustion.

*** Pendiente de traducción *** The Translate WordPress and go Multilingual – Weglot plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the &amp;#39;clean_options&amp;#39; function in all versions up to, and including, 5.1. This makes it possible for unauthenticated attackers to delete limited transients that contain cached plugin options.

*** Pendiente de traducción *** A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash.
