An OS command injection vulnerability exists in the Rapid7 InsightConnect Sed Plugin, allowing authenticated attackers to execute arbitrary system commands via the expression parameter.

Executive Summary:
An authenticated OS command injection vulnerability in the Rapid7 InsightConnect Sed Plugin allows attackers to execute arbitrary code on the underlying Linux host.

Vulnerability Details

CVE-ID: CVE-2026-9155

Affected Software: Rapid7 InsightConnect Sed Plugin

Affected Versions: See vendor advisory for specific affected versions

Vulnerability: This command injection vulnerability arises from insufficient input validation of the expression parameter within the plugin. An authenticated attacker can leverage this weakness to inject and execute arbitrary OS commands with the privileges of the application process.

The CVSS score of 8.8 reflects the high severity of full system compromise via remote command execution.

Remediation Plan

Immediate Action: Apply the vendor-provided security update for the InsightConnect Sed Plugin immediately to remediate the input validation failure.

Proactive Monitoring: Review logs for unusual process execution patterns or unexpected system calls originating from the InsightConnect service.

Compensating Controls: Enforce the principle of least privilege by running the plugin service under a restricted user account to limit the impact of a potential command injection.

Exploitation Status

Public Exploit Available: false

Analyst Notes: As of June 25, 2026, there is no public information indicating active exploitation of this vulnerability. However, due to the nature of the flaw, the potential for exploitation is high.

Analyst Recommendation

Command injection flaws are highly dangerous and often lead to full system compromise.

Vulnerability Details

CVE-ID: CVE-2026-74561

Affected Software: Linux Kernel

Affected Versions: Linux kernel versions up to (excluding) 7.1.8

Vulnerability: The vulnerability occurs because nh_rt_cache_flush performs an unlocked walk of the f6i_list while the list is being modified by concurrent IPv6 route operations. This race condition allows a local authenticated user to trigger a use-after-free scenario.

Business Impact

Exploitation of this vulnerability allows a local user with low privileges to escalate their access or cause a denial of service by crashing the kernel. With a CVSS score of 8.8, this flaw poses a severe risk to multi-tenant environments or systems where untrusted users have local access, as it can lead to full system compromise.

Remediation Plan

Immediate Action: Apply the latest kernel security updates, ensuring the kernel is updated to at least version 7.1.8.

Proactive Monitoring: Utilize kernel auditing tools to monitor for suspicious process behavior or unexpected kernel memory access errors.

Compensating Controls: Enforce strict access control policies to limit the number of users capable of executing network configuration commands that interact with the nexthop subsystem.

Executive Summary:
An unauthenticated attacker can disrupt network services by injecting malformed TCP packets to terminate connections, presenting a high risk to service availability.

Vulnerability Details

CVE-ID: CVE-2026-68118

Affected Software: Linux Kernel

Affected Versions: Linux Kernel versions prior to 6.18.42 and 7.1.6

Vulnerability: The Linux kernel TCP stack improperly handles RST packets in the SYN-RECEIVED state, allowing an off-path attacker to terminate half-open connections without requiring an exact sequence number match. This allows an unauthenticated remote attacker to disrupt connection establishment.

Business Impact

This vulnerability enables a remote denial of service attack against any service relying on TCP connections, which could result in significant service outages. With a CVSS score of 8.2, the high accessibility of this flaw makes it a critical concern for public-facing servers.

Remediation Plan

Immediate Action: Update the Linux kernel to versions 6.18.42, 7.1.6, or later, to correctly enforce TCP sequence number validation.

Proactive Monitoring: Review firewall and IDS logs for patterns of high volumes of TCP RST packets, which may indicate an ongoing denial of service attack.

Compensating Controls: Use stateful firewalls or load balancers that can perform deep packet inspection and filter out malformed TCP packets before they reach the kernel.

Exploitation Status

Public Exploit Available: false

Analyst Notes: As of August 10, 2026, there is no public information indicating active exploitation or a public proof-of-concept for this vulnerability. However, the nature of the flaw, which allows for remote, unauthenticated disruption of TCP services, makes it inherently attractive for exploitation.

Analyst Recommendation

Given the ease of exploitability and the potential for widespread service disruption, immediate patching is strongly recommended for all systems exposed to the internet. Administrators should prioritize this update to ensure the stability and availability of TCP-based network services.

Affected Software: Linux Kernel

Affected Versions: Linux kernel versions prior to 6.6.148, 6.12.101, 6.18.42, and 7.1.6, including version 5.15.

Vulnerability: This is an out-of-bounds heap read vulnerability within the ksmbd SMB server implementation, specifically occurring in the set_ntacl_dacl function. The vulnerability is triggered when an authenticated user provides a crafted security descriptor that fails to validate the sid.num_subauth field, resulting in the disclosure of approximately 1 KB of kernel memory.

Business Impact

The vulnerability carries a CVSS score of 8.1, indicating a high level of risk. Successful exploitation allows an authenticated attacker to read sensitive kernel memory, which may contain cryptographic keys, credentials, or other confidential system data. This poses a significant threat to data privacy and system integrity, as the exposure of such information could facilitate further unauthorized access or escalation of privileges.

Affected Versions: Linux kernel versions from 2.6.25 up to (excluding) 6.6.148, 6.12.101, 6.18.42, 7.1.6, and 7.2-rc5.

Vulnerability: This is a use-after-free vulnerability located within the Stream Control Transmission Protocol (SCTP) dynamic address reconfiguration logic. The flaw allows an attacker to interact with a freed transport object during DEL-IP processing, which can be triggered by a local user, including those within constrained environments like containers.

Business Impact

The CVSS score of 9.8 reflects the extreme severity of this flaw, as it enables full system compromise through local privilege escalation. Successful exploitation results in an attacker gaining root access, which facilitates data exfiltration, persistent malware installation, and the compromise of containerized workloads, potentially impacting the entire host infrastructure.

Remediation Plan

Immediate Action: Update the Linux kernel to version 6.6.148, 6.12.101, 6.18.42, 7.1.6, or 7.2-rc5 as provided by your distribution vendor.

Proactive Monitoring: Monitor system logs for unexpected kernel crashes, segmentation faults related to the sctp module, or suspicious attempts to load the sctp kernel module.

Compensating Controls: If immediate patching is not feasible, restrict the ability of unprivileged users to load the sctp kernel module using modprobe blacklisting (e.g., install sctp /bin/true in modprobe.d).

Exploitation Status

Public Exploit Available: Yes, multiple public proofs-of-concept are available on GitHub and other security research repositories.

Analyst Notes: As of August 4, 2026, there is no confirmed active exploitation in the wild; however, because the vulnerability was weaponized during research and multiple functional proofs-of-concept are publicly available, the risk of exploitation is high. The flaw is inherently dangerous due to its presence in core kernel networking code that is often automatically loaded on demand.

Analyst Recommendation

Given the critical severity of this vulnerability and the availability of public exploit code, organizations must prioritize patching the kernel across all affected environments, including container hosts. System administrators should verify kernel versions immediately and apply the stable updates provided by their respective distributions to prevent unauthorized root-level access.
