CVE-2016-10088
HighSummary
The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations when the KERNEL_DS option is set. This allows local users to read or write to arbitrary kernel memory locations and can cause a denial of service (use-after-free) by leveraging access to a /dev/sg device.
Risk Assessment
This vulnerability poses a risk to system integrity by allowing local users to manipulate kernel memory, potentially leading to serious security and stability issues.
Recommendation
It is recommended to update the Linux kernel to a version where this vulnerability has been fixed to minimize the risk associated with unauthorized access to kernel memory.

orval versions before 8.29.0 contain a code injection vulnerability in the @orval/hono generator that fails to escape OpenAPI path values in single-quoted route literals. Attackers can craft an OpenAPI document with an apostrophe in a static path segment to inject arbitrary JavaScript code that executes when the generated TypeScript module is imported.
- CVE-2026-95848Critical
Moquette is a lightweight Java MQTT broker. Prior to 0.18.1, when a configured authenticator or authorizator class cannot be loaded, Server.initializeAuthenticator and Server.initializeAuthorizatorPolicy treat the failure as though no custom class was configured and fall back to AcceptAllAuthenticator or PermitAllAuthorizatorPolicy. A misspelled class name, missing dependency, constructor failure, or classpath problem can therefore start the broker with authentication or authorization disabled even though the operator configured those controls. This issue is fixed in version 0.18.1.
- CVE-2026-85724Critical
Moquette is a lightweight Java MQTT broker. Prior to 0.18.1, when pattern-based ACL rules are configured, AuthorizationsCollector.canDoOperation substitutes client ID and username values directly into rules containing %c or %u and then treats the result as an MQTT topic filter. A client that uses + or # in either identity can broaden the substituted filter and gain cross-tenant read and write access. A # identity can also produce an invalid filter that triggers a NullPointerException in Topic.match and disrupts session processing. This issue is fixed in version 0.18.1.

IBM Financial Transaction Manager (FTM) for RedHat OpenShift is vulnerable to stored cross-site scripting (CWE-79) in the FTM UI NetworkAcknowledgement React component (NetworkAcknowledgement.jsx:42). A malicious actor can inject script into stored network acknowledgement data that executes in authenticated operator browsers, enabling session hijacking and unauthorized operator-level payment actions.

If a malicious SDK container declares an extension point with a crafted `directory` path, and a developer runs `flatpak build-init --writable-sdk --sdk-extension` with that SDK, attacker-chosen files could be written outside the working directory, since the target path is resolved via a function that allows `..` traversal.

LightLLM through 1.2.0 contains a remote code execution vulnerability in the KV-transfer worker when started with --pd_trans_mode nccl, which exposes an unauthenticated RPyC control channel that deserializes attacker-supplied data. Attackers can send malicious pickled objects to the exposed RPyC ThreadedServer to execute arbitrary code with the privileges of the LightLLM service account.
Original NVD description (English source)
The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576.
