CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2026-41709 Broadcom VMWare ESX Insufficient Logging Vulnerability CVE-2026-46300 Linux Kernel Missing Initialization of a Variable Vulnerability These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise.  Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA’s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied.  While BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities . CISA will continue to add vulnerabilities to the catalog that meet the specified criteria .  Aware of an expl...

Linux Kernel contains a missing initialization of a variable vulnerability that could allow for unintended modification of page-cache-backed data via failure to preserve the shared-fragment marker during socket buffer coalescing, causing ESP input processing to decrypt shared fragments in place. This vulnerability can be chained with CVE-2026-109618 and CVE-2026-109619 to implant PHP webshells and run commands as root.

Linux Kernel contains a race condition vulnerability which allows concurrent writes to the same AF_ALG socket causing data to be unpredictably interleaved and creating inconsistencies in the socket's internal state.

This vulnerability allows local attackers to disclose sensitive information on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The ZDI has assigned a CVSS rating of 6.0. The following CVEs are assigned: CVE-2026-43040.

View CSAF Summary Hitachi Energy is aware of Dirty Frag vulnerabilities that affect APM Edge product versions listed in this document. Successful exploitation of these vulnerabilities could result in impact on confidentiality, integrity and availability of the product. Please refer to the Recommended Immediate Actions for information about the mitigation/remediation. The following versions of Hitachi Energy APM Edge Product are affected: APM Edge vers:APM_Edge/<=6.10 (CVE-2026-43284, CVE-2026-43500) CVSS Vendor Equipment Vulnerabilities v3 8.8 Hitachi Energy Hitachi Energy APM Edge Product Write-what-where Condition, Out-of-bounds Write Background Critical Infrastructure Sectors: Energy Countries/Areas Deployed: Worldwide Company Headquarters Location: Switzerland Vulnerabilities Expand All + CVE-2026-43284 CWE-123: Write-what-where Condition A vulnerability exists in the IPsec ESP subsystem (esp4, esp6) of the Linux kernel used in APM Edge that allows a local unprivileged user to escalate privileges to root. The flaw exists in how the kernel handles memory pages when processing ESP encrypted network packets. An attacker can craft a packet that causes the kernel to decrypt data directly into memory pages it does not own, including the cached copies of privileged operating system binaries. When one of those binaries is executed, the attacker's injected code runs with root privilege...
