| In the Linux kernel, the following vulnerability has been resolved:
btrfs: reject root items with drop_progress and zero drop_level
[BUG]
When recovering relocation at mount time, merge_reloc_root() and
btrfs_drop_snapshot() both use BUG_ON(level == 0) to guard against
an impossible state: a non-zero drop_progress combined with a zero
drop_level in a root_item, which can be triggered:

---[ end trace 0000000000000000 ]---
The bug is reproducible on 7.0.0-rc2-next-20260310 with our dynamic
metadata fuzzing tool that corrupts btrfs metadata at runtime.
[CAUSE]
A non-zero drop_progress.objectid means an interrupted
btrfs_drop_snapshot() left a resume point on disk, and in that case
drop_level must be greater than 0 because the checkpoint is only
saved at internal node levels.
Although this invariant is enforced when the kernel writes the root
item, it is not validated when the root item is read back from disk.
That allows on-disk corruption to provide an invalid state with
drop_progress.objectid != 0 and drop_level == 0.
When relocation recovery later processes such a root item,
merge_reloc_root() reads drop_level and hits BUG_ON(level == 0). The
same invalid metadata can also trigger the corresponding BUG_ON() in
btrfs_drop_snapshot().
[FIX]
Fix this by validating the root_item invariant in tree-checker when
reading root items from disk: if drop_progress.objectid is non-zero,
drop_level must also be non-zero. Reject such malformed metadata with
-EUCLEAN before it reaches merge_reloc_root() or btrfs_drop_snapshot()
and triggers the BUG_ON.
After the fix, the same corruption is correctly rejected by tree-checker
and the BUG_ON is no longer triggered. |
| Uncontrolled resource consumption in .NET allows an unauthorized attacker to deny service over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: tegra - Add missing CRYPTO_ALG_ASYNC
The tegra crypto driver failed to set the CRYPTO_ALG_ASYNC on its
asynchronous algorithms, causing the crypto API to select them for users
that request only synchronous algorithms. This causes crashes (at
least). Fix this by adding the flag like what the other drivers do.
Also remove the unnecessary CRYPTO_ALG_TYPE_* flags, since those just
get ignored and overridden by the registration function anyway. |
| An external configuration control vulnerability in the OpenVPN module of TP-Link AX53 v1.0 allows an authenticated adjacent attacker to read arbitrary files when a malicious configuration file is processed. Successful exploitation may allow unauthorized access to arbitrary files on the device, potentially exposing sensitive information.This issue affects AX53 v1.0: before 1.7.1 Build 20260213. |

| CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. From version 0.26.0 to before version 0.31.8.0, the auth filter has the deactivated/banned user check commented out. This issue has been patched in version 0.31.8.0. |
| In Modem, there is a possible system crash due to incorrect error handling. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01753620; Issue ID: MSV-6100. |
| Vvveb before version 1.0.8.2 contains an XML external entity (XXE) injection vulnerability in the admin Tools/Import feature that allows authenticated site_admin users to read arbitrary files and modify database records. Attackers can exploit the XML parser configuration in system/import/xml.php to inject file:// or php://filter entity references that are resolved and persisted into the application database, enabling arbitrary file disclosure and administrator password hash overwriting for privilege escalation. |
| OpenCMS v20 and before is vulnerable to XML External Entity (XXE) in the Admin Import DB feature due to insecure XML parsing of user supplied .zip files containing a manifest.xml. |
| Unauthenticated attackers can exploit a weakness in the XML parser functionality of Lobster_pro prior to version 4.12.6-GA. This allows them to obtain read access to files on the application server and adjacent network shares, and perform HTTP GET requests to arbitrary services. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: replace BUG_ON with proper error handling in ext4_read_inline_folio
Replace BUG_ON() with proper error handling when inline data size
exceeds PAGE_SIZE. This prevents kernel panic and allows the system to
continue running while properly reporting the filesystem corruption.
The error is logged via ext4_error_inode(), the buffer head is released
to prevent memory leak, and -EFSCORRUPTED is returned to indicate
filesystem corruption. |
| The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This implementation results in predictable session identifiers and enables session hijacking or shadowing, where the most recent connection displaces the legitimate charging station and receives backend commands intended for that station. This vulnerability may allow unauthorized users to authenticate as other users or enable a malicious actor to cause a denial-of-service condition by overwhelming the backend with valid session requests. |
| XML External Entity (XXE) via Unsanitized Dictionary Parsing in Apache OpenNLP DictionaryEntryPersistor
Versions Affected: before 2.5.9, before 3.0.0-M3
Description: The DictionaryEntryPersistor class initializes a static SAXParserFactory at class-load time without enabling FEATURE_SECURE_PROCESSING or disabling DTD processing. When create(InputStream, EntryInserter) is invoked, the only feature set on the XMLReader is namespace support — external entity resolution and DOCTYPE declarations remain fully enabled. An attacker who can supply a crafted dictionary file (e.g., a stop-word list or domain dictionary) containing a malicious DOCTYPE declaration can trigger local file disclosure via file:// entity references or server-side request forgery via http:// entity references during SAX parsing, before the application processes a single dictionary entry. This is inconsistent with the project's own XmlUtil.createSaxParser() helper, which correctly sets FEATURE_SECURE_PROCESSING and disallow-doctype-decl and is used by all other XML parsing paths in the codebase. The public Dictionary(InputStream) constructor delegates directly to this method and is the documented API for loading user-supplied dictionaries, making untrusted input a realistic scenario.
Mitigation: 2.x users should upgrade to 2.5.9. 3.x users should upgrade to 3.0.0-M3. Users who cannot upgrade immediately should ensure that all dictionary files are sourced from trusted origins and should consider wrapping the Dictionary(InputStream) constructor with input validation that rejects any XML containing a DOCTYPE declaration before it reaches the parser. |

| OpenClaw versions 2026.3.22 before 2026.4.5 contain a symlink traversal vulnerability in remote marketplace repository path handling that allows attackers to escape the expected repository root. Attackers can exploit this by providing crafted symlink paths to access files outside the intended repository directory. |
| Tunnelblick is an open source graphic user interface for OpenVPN on macOS. In versions 3.3beta26 through 9.0beta01, any local user can read arbitrary root-owned files by exploiting a symlink following vulnerability in tunnelblick-helper, reachable through the world-accessible tunnelblickd Unix socket. The socket is configured with mode 0666, allowing any local user to connect. No authorization check is performed on the connecting client. The tunnelblick-helper process constructs a path to config.ovpn inside a user-controlled .tblk directory and reads it as root without symlink validation. An attacker can create a .tblk configuration with a symlinked config.ovpn pointing to any file and request tunnelblickd to read it. This issue has been fixed in versions 9.0beta02. |
