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.

  • 9.1 /10 Critical
    CVE-2026-89713

    Linux Kernel NFSD - Race Condition

    Linux kernel NFSD contains a time-of-check to time-of-use (TOCTOU) vulnerability caused by checking truncate permission without inode lock, letting attackers bypass append-only file restrictions during concurrent file size changes, exploit requires concurrent file append operations.

  • 9.8 /10 Critical
    CVE-2026-89712

    Linux Kernel - Use After Free

    Linux kernel contains a use-after-free vulnerability in NFSD nfsd4_ssc_expire_umount caused by improper handling of list iteration after dropping nfsd_ssc_lock, letting attackers cause denial of service by crashing the kernel, exploit requires concurrent NFS RPC threads.

  • 8.2 /10 High
    CVE-2026-89711 No auth

    Linux kernel NFSD - Broken Authentication

    Linux kernel NFSD contains a broken authentication vulnerability caused by flawed WARN_ON_ONCE usage in nfsd_mode_check, letting attackers cause improper error handling during NFS reexport, exploit requires NFS filesystem export with specific dentry conditions.

  • 8.1 /10 High
    CVE-2026-89709

    Linux Kernel - Use After Free

    Linux kernel contains a use-after-free vulnerability in lockd and nfsd due to unguarded dereference of nlmsvc_ops pointer after module removal, letting attackers cause kernel crashes or code execution, exploit requires module unloading.

  • 9.8 /10 Critical
    CVE-2026-89708 No auth

    Linux Kernel - Use After Free

    Linux kernel contains a use-after-free vulnerability in nfsd caused by improper handling of cl_cb_session during session teardown, letting attackers cause memory corruption or denial of service, exploit requires triggering session destruction with inflight callbacks.

  • 7.5 /10 High
    CVE-2026-89707 No auth

    Linux Kernel - Resource Leak

    Linux kernel contains a resource leak vulnerability in nfsd_cross_mnt() due to missing release of path references on follow_down() error, letting authenticated NFS clients cause resource exhaustion, exploit requires authenticated NFS client access.

  • 7.5 /10 High
    CVE-2026-89706 No auth

    Linux kernel nfsd - Broken Access Control

    Linux kernel nfsd contains a broken access control vulnerability caused by failure to reset write verifier on async COPY writeback failure, letting NFS clients incorrectly assume data durability, exploit requires NFS client interaction.

  • 7.1 /10 High
    CVE-2026-89705 Auth required

    Linux Kernel - Broken Access Control

    Linux kernel contains a broken access control vulnerability in nfsd_dispatch() caused by improper restoration of rq_status_counter on all exit paths, letting attackers cause data races and inconsistent state exposure, exploit requires kernel-level access.

  • 7.5 /10 High
    CVE-2026-89704 No auth

    Linux Kernel nfsd - Silent Data Loss

    Linux kernel contains a silent data loss vulnerability in nfsd due to improper sampling of writeback error cursor in nfsd_copy_file_range, letting attackers cause undetected writeback failures during async COPY operations, exploit requires concurrent COMMIT or stable WRITE on destination file.

  • 9.8 /10 Critical
    CVE-2026-89703

    Linux Kernel - Use After Free

    Linux kernel contains a use-after-free vulnerability in nfsd4_drop_revoked_stid due to missing SC_STATUS_FREED flag setting for admin-revoked delegations, letting attackers cause memory corruption, exploit requires local access.

  • 9.8 /10 Critical
    CVE-2026-89702 No auth

    Linux Kernel - Out of Bounds Read/Write

    Linux kernel contains a buffer overflow caused by mismatched sizing of server sockaddr slot in nfsd_fh_verify tracepoints, letting attackers cause out-of-bounds memory writes, exploit requires NFS/UDP usage.

  • 7.5 /10 High
    CVE-2026-89699 No auth

    Linux Kernel - Denial of Service

    Linux kernel contains a denial of service caused by unbounded symlink target length allocation in nfsd4_decode_create for NFSv4 CREATE, letting remote attackers exhaust memory, exploit requires sending crafted NFSv4 CREATE requests.

  • 9.1 /10 Critical
    CVE-2026-89697 No auth

    Linux Kernel - Broken Access Control

    Linux kernel contains a broken access control vulnerability caused by missing fh_want_write() call in nfsd_proc_setattr() during early-verified SETATTR, letting attackers cause improper mount write reference handling, exploit requires network access to NFS service.

  • 7.5 /10 High
    CVE-2026-89696 No auth

    Linux Kernel nfsd - Denial of Service

    Linux kernel nfsd with CONFIG_NFSD_V4_2_INTER_SSC enabled contains a NULL pointer dereference caused by improper handling of FOREIGN PUTFH in nfsd4_putfh, letting remote clients cause a denial of service via crafted COMPOUND requests, exploit requires crafted inter-SSC COPY with inserted operations.

  • 7.5 /10 High
    CVE-2026-89695 No auth

    Linux Kernel - Denial of Service

    Linux kernel contains a denial of service vulnerability in nfsd4_decode_posixacl() caused by uncapped POSIX ACL entry count leading to unbounded CPU usage in sort_pacl_range(), letting remote attackers cause high CPU load, exploit requires crafted NFS requests.
