| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to execute arbitrary code due to a heap-based buffer overflow. |
| In the Linux kernel, the following vulnerability has been resolved:
kernfs: fix xattr race condition with multiple superblocks
Multiple superblocks with different namespaces can share the same
kernfs_node when kernfs_test_super() finds a matching root but
different namespace. This means multiple inodes from different
superblocks can reference the same kernfs_node->iattr->xattrs
structure.
The VFS layer only holds per-inode locks during xattr operations,
which is insufficient to serialize concurrent xattr modifications on
the shared kernfs_node. This can lead to race conditions in
simple_xattr_set() where the lookup->replace/remove sequence is not
atomic with respect to operations from other superblocks.
Fix this by protecting xattr operations with the existing hashed
kernfs_locks->open_file_mutex[] array, which is already used to
protect per-node open file data. The hashed mutex array provides
scalable per-node serialization (scaled by CPU count, up to 1024 locks
on 32+ CPU systems) with zero memory overhead.
Changes:
- Rename open_file_mutex[] to node_mutex[] to reflect dual purpose
- Add kernfs_node_lock_ptr() and kernfs_node_lock() helpers
- Protect simple_xattr_set() calls in kernfs_xattr_set() and
kernfs_vfs_user_xattr_set() with the hashed mutex
- Update file.c to use new helpers via compatibility wrappers
- Update documentation to explain the extended lock usage |
| An authenticated authorization bypass vulnerability exists in MCP Toolbox for Databases due to missing scope enforcement across older protocol handlers.
While the 2025-11-25 protocol version handler correctly enforces per-tool restrictions defined by scopesRequired, older supported protocol versions (2025-06-18, 2025-03-26, and 2024-11-05) omit this check. An authenticated client with low-privilege tokens (e.g., read) can bypass the intended per-tool scope restrictions and execute high-privilege tools (e.g., admin) simply by specifying an older protocol version in the MCP-Protocol-Version header, or by omitting the header entirely (which causes the server to default to the vulnerable 2024-11-05 handler). |

| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to cause a denial of service and obtain sensitive information due to an integer underflow. |
| Stack-based buffer overflow in Windows DNS allows an unauthorized attacker to execute code over a network. |
| In Roundcube Webmail before 1.6.18 and 1.7.x before 1.7.3, the "Add to address book" action was subject to stored XSS. |
| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to obtain sensitive information due to a heap buffer overflow. |
| IBM i 7.6, 7.5, and 7.4 s vulnerable to SQL injection. A remote attacker could send specially crafted SQL statements, which could allow the attacker to view, add, modify, or delete information in the back-end database. |
| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a local attacker to execute arbitrary code due to an out-of-bounds write. |
| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to delete arbitrary files due to path traversal. |
| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to bypass security restrictions due to improper validation of anti-CSRF tokens. |
| A reflected cross-site scripting issue exists in URL handling. |
| Exposed methods allow authenticated users to create and execute arbitrary JavaScript code on the server. The scripts execute with full access, enabling complete system compromise as commands are executed as root. |
| Heap-based buffer overflow in Windows Brokering File System allows an authorized attacker to elevate privileges locally. |
| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to cause a denial of service due to unbounded resource allocation. |
