The Rocky Linux 9 host has packages installed that are affected by a vulnerability as referenced in the CIQ crlsa-20244636 advisory. libndp: buffer overflow in route information length field CVE-2024-5564 Tenable has extracted the preceding description block directly from the CIQ security advisor...

Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: iperf3 (UTSA-2023-002138)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2023-002138 advisory. iperf3 before 3.14 allows peers to cause an integer overflow and heap corruption via a crafted length field. Tenable has extracted the preceding description block...

CVE-2026-65979

A flaw was found in OpenEXR's HTJ2K decoder. A local user could be tricked into opening a specially crafted EXR image file. When processed, the decoder reads beyond the bounds of an allocated buffer due to an unvalidated header length field. This out-of-bounds read can lead to a denial of service...

CVE-2026-82435

Apache Storm workers are vulnerable to unauthenticated remote memory exhaustion due to the placement of the Netty message decoder in the pipeline. Because the decoder is installed ahead of SASL authentication handlers, it processes frames before credentials are verified. An unauthenticated peer w...

Astra Linux – Vulnerability in Wireshark

In Wireshark versions 3.2.0 to 3.2.1, 3.0.0 to 3.0.8, and 2.6.0 to 2.6.14, the WiMax DLMAP dissector could crash. This issue was addressed in the plugin plugins/epan/wimax/msgdlmap.c by validating the length field...

CVE-2026-89495

In the Linux kernel, the following vulnerability has been resolved: ocfs2: bound namelen in dlmmigraterequesthandler Patch series "ocfs2/dlm: bound peer-controlled lengths in the o2dlm". The o2dlm receive handlers trust u8 length and count fields from the wire without bounding them, so a node in ...

EUVD-2026-72341

In Eclipse Ankaios versions 0.1.0 through 1.0.1, the agent does not limit the length declared by a workload in a length-delimited protobuf message received through the Control Interface FIFO. A workload granted Control Interface access can specify an excessive message length, causing an unbounded...

CVE-2026-85437

MOOS-IvP through version 24.8.1 is affected by multiple buffer overflow vulnerabilities in its IvP function string decoders (specifically in FunctionEncoder.cpp). The root cause is that decoders trust attacker-controlled length fields without validation, allowing an attacker to craft malicious en...

SUSE CVE-2026-70405

Improper Validation of Specified Quantity in Input vulnerability in Erlang/OTP snmp allows a remote attacker to degrade availability by sending an SNMP message containing a BER INTEGER whose length field is arbitrarily large. snmppdus:decintegernotag/1 defaults its size limit to infinity, and...

CVE-2026-80594

A flaw was found in the Linux kernel's ims-pcu driver. This vulnerability allows a malicious device to trigger an infinite loop by providing a specially crafted descriptor with a zero-length field during the parsing of CDC union descriptors. This can lead to a Denial of Service DoS condition,...

kernel: net: openvswitch: reject oversized nested action attrs

A flaw was found in Open vSwitch in the Linux kernel. Improper handling of oversized nested action attributes can lead to a truncated length field, which could be exploited by a local attacker to alter kernel memory. This alteration might result in the disclosure of sensitive information or a loc...

GHSA-HMQ9-67W8-J5PW netty-incubator-codec-ohttp: BinaryHttpParser should enforce limits for variable lengths fields

We don't enforce any limits for the encoded variable lengths that are used for fields. As the remote peer controls these it's easy for the remote peer to have us buffer data forever and so ultimately OOM...
