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-2026-89692 No auth

    Linux Kernel - Broken Access Control

    Linux kernel contains a broken access control vulnerability caused by improper clearing of CALLBACK_RUNNING flag in nfsd delegation recall queue, letting attackers cause delegation recall to stall, exploit requires triggering delegation recall failure.

  • 7.1 /10 High
    CVE-2026-89691 Auth required

    Linux Kernel - Information Disclosure

    Linux kernel contains an information disclosure vulnerability in nfsd4_release_compoundargs() caused by not clearing opcnt on compound arg release, letting attackers leak adjacent kernel memory via netlink, exploit requires crafted RPC requests.

  • 7.8 /10 High
    CVE-2026-89690 Auth required

    Linux Kernel - Use After Free

    Linux kernel contains a use-after-free vulnerability in nfsd caused by premature freeing of vmalloc buffer in nfsd4_release_compoundargs, letting attackers cause memory corruption during concurrent compound completion, exploit requires concurrent NFSv4 compound requests.

  • 9.8 /10 Critical
    CVE-2026-89689 No auth

    Linux Kernel nfsd - Use After Free

    Linux kernel nfsd contains a use-after-free vulnerability caused by improper freeing of session slots in nfsd4_sequence(), letting attackers cause memory corruption and potential denial of service, exploit requires crafted NFSv4 client requests.

  • 9.8 /10 Critical
    CVE-2026-89688 No auth

    Linux Kernel - Use After Free

    Linux kernel contains a use-after-free vulnerability caused by incorrect reference counting in nfsd4_cstate_assign_replay() during seqid_op replay retry, letting attackers cause memory corruption or denial of service, exploit requires attacker to trigger specific NFSv4 operations.

  • 7.5 /10 High
    CVE-2026-89687 No auth

    Linux Kernel - Broken Access Control

    Linux kernel contains a broken access control vulnerability caused by nfsd_file_do_acquire() using files not confirmed as opened, letting attackers potentially cause improper file handling, exploit requires NFS server interaction.

  • 9.8 /10 Critical
    CVE-2026-89686 No auth

    Linux Kernel - Denial of Service

    Linux kernel contains a race condition in nfsd4_alloc_layout_stateid caused by unsynchronized access to fi_deleg_file during delegation revoke, letting NFS clients trigger a kernel BUG, exploit requires concurrent NFS clients with delegation and recall.

  • 7.5 /10 High
    CVE-2026-89685 No auth

    Linux Kernel - Denial of Service

    Linux kernel contains a denial of service caused by a clock domain mismatch in clients_still_reclaiming(), letting any client hold the NFS server in grace indefinitely by sending CLAIM_PREVIOUS OPEN requests, exploit requires network access to send crafted requests.

  • 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.
