Technical summary
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: ensure no dangling hcon references in iso_conn After iso_conn_del(), ISO sockets should not dereference the hcon any more. Currently, clearing iso_conn::hcon relies on iso_conn_del() releasing the last reference to the iso_conn. Simplify this by explicitly clearing conn->hcon in iso_conn_del(), to avoid more complex reasoning on races about who holds the last reference.

About the Vulnerability Pulse CVE Feed
The Vulnerability Pulse feed tracks live CVE advisories sourced from the National Vulnerability Database and vendor security disclosures. It is designed for SOC analysts, IT administrators, and security teams who need a fast, filterable view of current vulnerabilities without digging through raw NVD data.
How to Use the CVE Advisory Tracker
Use the severity filters to narrow results to Critical or High priority vulnerabilities. Filter by vendor to focus on software and hardware relevant to your environment. Export to CSV for reporting, ticketing, or patch prioritization workflows.
What Is a CVE Advisory?
A CVE (Common Vulnerabilities and Exposures) advisory is a public disclosure of a security vulnerability assigned a unique identifier by MITRE. Advisories include severity scores (CVSS), affected versions, and remediation guidance. Monitoring CVE advisories is a core function of vulnerability management programs and SOC operations.
CVE Analysis & Writeups
For in-depth analysis of specific vulnerabilities, visit the IT Knowledge Bases blog for CVE breakdowns, exploitation analysis, and remediation guidance written for security practitioners.
