Title
Omni is Vulnerable to DoS via Empty Create/Update Resource Requests
Summary
Omni manages Kubernetes on bare metal, virtual machines, or in a cloud. Prior to 1.1.5 and 1.0.2, there is a nil pointer dereference vulnerability in the Omni Resource Service allows unauthenticated users to cause a server panic and denial of service by sending empty create/update resource requests through the API endpoints. The vulnerability exists in the isSensitiveSpec function which calls grpcomni.CreateResource without checking if the resource's metadata field is nil. When a resource is created with an empty Metadata field, the CreateResource function attempts to access resource.Metadata.Version causing a segmentation fault. This vulnerability is fixed in 1.1.5 and 1.0.2.

Title
Junos OS Evolved: ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509: When specific valid multicast traffic is received on the L3 interface on a vulnerable device evo-pfemand crashes and restarts
Summary
A NULL Pointer Dereference vulnerability in the PFE management daemon (evo-pfemand) of Juniper Networks Junos OS Evolved on ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509 devices allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS). Whenever specific valid multicast traffic is received on any layer 3 interface the evo-pfemand process crashes and restarts. Continued receipt of specific valid multicast traffic results in a sustained Denial of Service (DoS) attack. This issue affects Junos OS Evolved on ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509:  * from 23.2R2-EVO before 23.2R2-S4-EVO,  * from 23.4R1-EVO before 23.4R2-EVO. This issue affects IPv4 and IPv6. This issue does not affect Junos OS Evolved ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7348, ACX7509 versions before 23.2R2-EVO.

CVE-2025-60007 (GCVE-0-2025-60007)

Vulnerability from cvelistv5 – Published: 2026-01-15 20:16 – Updated: 2026-03-16 18:18

Title
Junos OS: A specifically crafted 'show chassis' command causes chassisd to crash
Summary
A NULL Pointer Dereference vulnerability in the chassis daemon (chassisd) of Juniper Networks Junos OS on MX, SRX and EX Series allows a local attacker with low privileges to cause a Denial-of-Service (DoS). When a user executes the 'show chassis' command with specifically crafted options, chassisd will crash and restart. Due to this all components but the Routing Engine (RE) in the chassis are reinitialized, which leads to a complete service outage, which the system automatically recovers from. This issue affects: Junos OS on MX, SRX and EX Series, except MX10000 Series and MX304:  * all versions before 22.4R3-S8, * 23.2 versions before 23.2R2-S5, * 23.4 versions before 23.4R2-S6, * 24.2 versions before 24.2R2-S2, * 24.4 versions before 24.4R2.

Title
Glib-networking: uninitialized memory dereferences on glib-networking through glib-networking/tls/openssl/gtlsbio.c via g_tls_bio_new_from_iostream() and g_tls_bio_new_from_datagram_based()
Summary
glib-networking's OpenSSL backend fails to properly check the return value of memory allocation routines. An out of memory condition could potentially result in writing to an invalid memory location.

CVE-2025-61908 (GCVE-0-2025-61908)

Vulnerability from cvelistv5 – Published: 2025-10-16 17:16 – Updated: 2025-10-16 19:23

Title
Icinga 2 Denial of Service (DoS) By Dereferencing Invalid Reference
Summary
Icinga 2 is an open source monitoring system. From 2.10.0 to before 2.15.1, 2.14.7, and 2.13.13, when creating an invalid reference, such as a reference to null, dereferencing results in a segmentation fault. This can be used by any API user with access to an API endpoint that allows specifying a filter expression to crash the Icinga 2 daemon. A fix is included in the following Icinga 2 versions: 2.15.1, 2.14.7, and 2.13.13.

CVE-2025-62409 (GCVE-0-2025-62409)

Vulnerability from cvelistv5 – Published: 2025-10-16 17:47 – Updated: 2025-10-16 19:22
VLAI
Title
Envoy allows large requests and responses to cause TCP connection pool crash
Summary
Envoy is a cloud-native, open source edge and service proxy. Prior to 1.36.1, 1.35.5, 1.34.9, and 1.33.10, large requests and responses can potentially trigger TCP connection pool crashes due to flow control management in Envoy. It will happen when the connection is closing but upstream data is still coming, resulting in a buffer watermark callback nullptr reference. The vulnerability impacts TCP proxy and HTTP 1 & 2 mixed use cases based on ALPN. This vulnerability is fixed in 1.36.1, 1.35.5, 1.34.9, and 1.33.10.

Mitigation ID: MIT-56

Phase: Implementation

Description:

  • For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation

Phase: Requirements

Description:

  • Select a programming language that is not susceptible to these issues.
Mitigation

Phase: Implementation

Description:

  • Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation

Phase: Architecture and Design

Description:

  • Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation

Phase: Implementation

Description:

  • Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
