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.

  • 7.5 /10 High
    CVE-2026-89684 No auth

    Linux Kernel - Race Condition

    Linux kernel contains a race condition in nfsd's nfs4_init_cp_state caused by improper locking during cpntf state publishing, letting NFSv4.2 clients cause server crashes via OFFLOAD_CANCEL, exploit requires NFSv4.2 client interaction.

  • 8.1 /10 High
    CVE-2026-89682

    Linux Kernel - Use After Free

    Linux kernel contains a use-after-free vulnerability in nfsd due to a separately allocated fcache disposal structure being freed prematurely, letting attackers cause memory corruption, exploit requires triggering nfsd file disposal during net namespace teardown.

  • 9.8 /10 Critical
    CVE-2026-89681 No auth

    Linux Kernel - Race Condition

    Linux kernel contains a race condition in nfsd layout fence worker caused by double-reference of sc_count in lm_breaker_timedout, letting attackers cause resource leaks, exploit requires local access.

  • 7.5 /10 High
    CVE-2026-89680

    Linux Kernel - Resource Leak

    Linux kernel contains a resource leak vulnerability caused by improper error handling in nfsd4_setup_inter_ssc during inter-server COPY setup failure, letting attackers cause resource exhaustion, exploit requires triggering inter-server COPY failure.

  • 7.5 /10 High
    CVE-2026-89679 No auth

    Linux Kernel - Denial of Service

    Linux kernel contains a null pointer dereference in nfsd4_setattr caused by improper handling of special NFSv4 stateid in delegation timestamp attributes, letting remote NFSv4 clients cause kernel crash without authentication.

  • 7.5 /10 High
    CVE-2026-89678 No auth

    Linux Kernel - Data Tampering

    Linux kernel contains a data tampering vulnerability in nfsd_direct_write caused by incorrect partial-write detection, letting attackers cause file offset corruption and data over-reporting, exploit requires NFS client interaction.

  • 9.8 /10 Critical
    CVE-2026-89677

    Linux Kernel - Use After Free

    Linux kernel contains a use-after-free vulnerability in nfsd4_create_file caused by improper handling of dentry in fh_compose, letting attackers cause memory corruption, exploit requires NFS exported filesystem with specific filehandle conditions.

  • 9.8 /10 Critical
    CVE-2026-89676 No auth

    Linux Kernel - Use After Free

    Linux kernel contains a use-after-free vulnerability in nfsd async COPY caused by stale s2s_cp_stateids IDR entry pointing to transient request memory, letting attackers cause memory corruption or denial of service, exploit requires triggering async COPY operations.

  • 9.8 /10 Critical
    CVE-2026-89675 No auth

    Linux kernel nfsd - Use After Free

    Linux kernel nfsd contains a use-after-free vulnerability caused by race conditions in async copy cancel and shutdown operations, letting local attackers cause memory corruption or kernel crashes, exploit requires concurrent async copy operations.

    CVE-2026-89674 No auth

    Linux Kernel - Buffer Overflow & Information Disclosure

    Linux kernel contains a buffer overflow and information disclosure vulnerability caused by incorrect XDR length calculation in nfsd4_ff_encode_layoutget, letting remote attackers cause out-of-bounds write or leak uninitialized kernel memory, exploit requires crafted NFSv4 requests.

  • 9.1 /10 Critical
    CVE-2026-89672 No auth

    Linux Kernel NFSd - Broken Access Control

    Linux kernel NFS server (nfsd) contains a broken access control vulnerability in NFSACL v2 SETACL path caused by improper handling of ACL mask bits, letting attackers silently remove ACLs, exploit requires crafted NFS SETACL requests.

  • 9.1 /10 Critical
    CVE-2026-89671 No auth

    Linux Kernel - Broken Access Control

    Linux kernel contains a broken access control vulnerability in nfsd3_proc_setacl where ACL mask bits are not checked before setting ACLs, letting remote attackers unintentionally remove ACLs, exploit requires crafted NFSv3 SETACL request.

  • 7.8 /10 High
    CVE-2026-89670

    Linux Kernel - Use After Free
