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 HighCVE-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 CriticalCVE-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 CriticalCVE-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 HighCVE-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 CriticalCVE-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 HighCVE-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 HighCVE-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.
- 7.5 /10 HighCVE-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 HighCVE-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 HighCVE-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 CriticalCVE-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 CriticalCVE-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 HighCVE-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 CriticalCVE-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 HighCVE-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.
