Threat Heartbeat

New CVEs as they are published, with CVSS score, CISA KEV status, public exploits and the vendor's fix. Worth tracking, but only a small part of what Panop does: mapping what you expose to the internet, testing what an attacker can actually exploit, ranking it by business impact, and helping your team understand and fix it.

  • 7.8 /10 High
    CVE-2026-89670

    Linux Kernel - Use After Free

    Linux kernel contains a use-after-free vulnerability in nfsd_file objects due to missing RCU locking around cmpxchg in nfsd_open_local_fh, letting attackers cause memory corruption or denial of service, exploit requires local code execution.

  • 9.8 /10 Critical
    CVE-2026-89669 No auth

    Linux Kernel - Use After Free

    Linux kernel contains a use-after-free vulnerability in nfsd4_copy_notify due to improper initialization and publication order of copy-notify stateid, letting remote attackers cause memory corruption via racing OFFLOAD_CANCEL, exploit requires crafted network requests.

  • 7.8 /10 High
    CVE-2026-89668 Auth required

    Linux Kernel - Resource Management Issue
