High CVEs
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-2026-89696 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.
- 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.
- 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.
- 7.5 /10 HighCVE-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 HighCVE-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.
- 7.5 /10 HighCVE-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 HighCVE-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 HighCVE-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.
- 7.8 /10 HighCVE-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.
- 7.8 /10 HighCVE-2026-89668 Auth required
Linux Kernel - Resource Management Issue
Linux kernel contains a resource management vulnerability caused by improper initialization order in nfsd_debugfs_init() and nfsd4_init_slabs(), letting kernel modules leave orphan debugfs files with stale pointers, exploit requires slab allocation failure.
- 8.1 /10 HighCVE-2026-89667 No auth
Linux Kernel - Race Condition
Linux kernel contains a race condition in nfsd filecache caused by improper synchronization of shrinker, GC worker, and fsnotify/lease callbacks with per-net shutdown, letting attackers cause resource leaks, exploit requires concurrent operations.
