xfs: fix the rtrmap and rtrefcount _maxlevels_ondisk functions

In the Linux kernel, the following vulnerability has been resolved: xfs: fix the rtrmap and rtrefcount _maxlevels_ondisk functions The _maxlevels_ondisk functions are used to compute the size of in-memory btree cursors for each btree type. Unfortunately, LOLLM noticed that the rtrmap and rtrefcount versions of these functions forget to account for the inode root, which means that we could access beyond the end of the cursor given a sufficiently large btree. Fix this.

afs: Clear stale peer app data after address list changes

In the Linux kernel, the following vulnerability has been resolved: afs: Clear stale peer app data after address list changes afs_fs_probe_fileserver() fetches the current endpoint state under server->fs_lock, but leaves old_alist as NULL. Consequently, afs_set_peer_appdata() treats every address list replacement as initial setup and only binds the new peers; it never unbinds peers removed from the old list. An address refresh can therefore proceed as follows. CPU 0 replaces server S's list and drops Pold without clearing Pold->app_data. The server destroyer then clears only S's current peers and lets S reach its RCU callback. After the callback frees S, CPU 1 handles a callback through an RxRPC connection that still pins Pold, reads Pold->app_data, and calls afs_use_server() on the freed object.

afs: Fix incorrect free in candidate cleanup in afs_lookup_server()

In the Linux kernel, the following vulnerability has been resolved: afs: Fix incorrect free in candidate cleanup in afs_lookup_server() Fix afs_lookup_server() to not free an existing server's endpoint state when cleaning up a candidate server. The candidate record doesn't have an endpoint state yet at this point, so the free for that can just be removed.

afs: Fix double-unmap of directory block

In the Linux kernel, the following vulnerability has been resolved: afs: Fix double-unmap of directory block Fix afs_edit_dir_remove() to use a cleanup function to unmap the block pointed to by afs_dir_iter::block if it's left pointing to something rather than manually kunmapping the blocks. Manually kunmapping without clearing iter.blocks can result in a double-kunmap if afs_dir_find_block() is called twice in a row (which would be the case if the block being modified is not first in the hash chain).

Missing Authentication

Esri Portal for ArcGIS versions 12.1 and earlier on Windows, Linux and Kubernetes have a missing authentication for critical function vulnerability allows a remote, unauthenticated attacker to access an unprotected API. The following versions are known to be affected: Portal for ArcGIS 12.1 and earlier. Other unsupported versions may also be affected. Esri recommends that users apply the Portal for ArcGIS Security 2026 Update 2 Patch to remediate this vulnerability.

Race Condition in MongoDB Server Document Value Layer Leads to Memory Corruption

A race condition in the document value layer of MongoDB Server can allow concurrent server threads to operate on the same internal memory without synchronization, leading to memory corruption. An authenticated user holding ordinary read-write privileges on a database may be able to trigger this condition over the normal client protocol, resulting in server termination and potential corruption of process memory with user-influenced content. Successful use of this issue may impact the confidentiality, integrity, and availability of the affected server process.

Windows Secure Kernel Mode Elevation of Privilege Vulnerability

Double free in Windows Secure Kernel Mode allows an authorized attacker to elevate privileges locally.

Heap overflow via oversized decrypted TLS record sequence in Windows Secure Channel stream

A heap-based buffer overflow exists in the TLS transport layer of the MongoDB C Driver when built with the Windows platform TLS backend. A remote endpoint that the client connects to can cause the driver to write uncontrolled data outside the bounds of a heap allocation while processing incoming encrypted traffic after the TLS handshake completes. No authentication or user interaction is required, because the affected processing occurs before any application-level authentication completes. Triggering this issue may lead to memory corruption in the client process, disclosure of adjacent heap memory, or termination of the process.

mathurvishal CloudClassroom-PHP-Project managevideos2.php sql injection

A vulnerability has been found in mathurvishal CloudClassroom-PHP-Project up to 5dadec098bfbbf3300d60c3494db3fb95b66e7be. Affected by this vulnerability is an unknown functionality of the file managevideos2.php. Such manipulation of the argument editassid leads to sql injection. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. The vendor was contacted early about this disclosure but did not respond in any way.

X-SpringBoot through 6.0 Authorization Bypass via User Management

X-SpringBoot through 6.0 lacks object-level authorization in user management endpoints, allowing sub-administrators to modify or delete users without ownership verification. Attackers with user-management permissions can reset passwords for any account including the super administrator, rebind roles, or delete users via POST /sys/user/update and POST /sys/user/delete endpoints.

Cross-database write retargeting via unvalidated dotted database name in Client.BulkWrite in the MongoDB Go Driver

The MongoDB Go Driver's client-level bulk write operation may accept a caller-supplied database name containing a reserved separator character without escaping it before the name is used to build the target namespace for the operation. An application that passes untrusted input as a database name could therefore have the write directed at a database and collection other than the ones it intended. Only the Client.BulkWrite API is affected.

Concrete CMS 9.0.0 to 9.5.2 is vulnerable to Stored XSS in Custom Page Alias Name

Concrete CMS 9.0.0 through 9.5.3 is vulnerable to stored XSS via the custom page alias name (customAliasName) because the Edit Alias dialog applied only trim() to the submitted value and performed no input neutralization. An authenticated user holding canWrite (editor) permission on a page could store a malicious alias name that was later rendered unescaped in the administrative Sitemap panel, where it executed automatically in any administrator or editor session that opened the panel, allowing an editor to escalate to administrator through the victim's active session. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 7.3 with vector CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:P/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N.

Zammad: S/MIME signature verification allows forged sender impersonation

Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, when Zammad checks the digital signature on an incoming S/MIME-signed email, it does not verify that the signing certificate is genuinely trusted, it only checks whether a certificate with a matching name is already stored in the system. An attacker can create their own certificate using the name of a real, previously trusted sender and use it to send a forged email. Zammad will display that email with the same "validly signed" indicator as a genuine message from the real sender, even though the attacker never had access to that sender's actual certificate or private key. This issue is fixed in version 7.1.2.

Zammad: Missing Authorization in TagsController#list Allows Cross-Object Tag Enumeration

Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, any authenticated user can call the REST endpoint for getting a tag list and receive the tag names for the given ticket, regardless of whether they have access to that ticket. Tags are an internal categorization feature and may contain sensitive labels. Ticket IDs are sequential integers, making bulk enumeration straightforward. This issue is fixed in version 7.1.2.

Zammad: Sensitive Information Exposure in Integration Administration API

Zammad is a web based open source helpdesk/customer support system. In 7.0.3 and 7.1.1, an authenticated administrator can obtain stored integration credentials in cleartext through the integration administration API. Certain responses do not consistently mask sensitive fields, so configured secrets can be returned in plain text instead of the expected masked placeholder. Both the LDAP and Exchange integrations are affected. This issue is fixed in version 7.1.2.
