from its metadata and data servers; a malicious or compromised pNFS server can return layout-state errors that lead to the client crash.\nAC:L - The server controls layout ranges, data-server replies, and stateid-error timing, allowing it to establish a pending layoutcommit and then invalidate the last layout segment without relying on an uncontrollable race.\nPR:N - The attacker needs no account or capability on the client; CAP_SYS_ADMIN is required only for the victim's initial NFS mount, and ordinary deployments may use unauthenticated AUTH_SYS server communication.\nUI:N - In a pre-mounted pNFS or NFS-root deployment, automated writes and kernel writeback can complete the trigger sequence without human action at exploitation time.\nS:U - The resulting failure affects the NFS client kernel within its existing security authority and does not cross a virtualization, sandbox, or IOMMU boundary.\nC:N - The stale flag causes a direct NULL dereference of the absent layout rather than an out-of-bounds read, use-after-free access, or information-disclosure primitive.\nI:N - The defect does not provide an attacker-controlled write or corrupt adjacent memory; execution faults while attempting to traverse the layout segment list through a NULL layout pointer.\nA:H - The NULL dereference occurs in kernel writeback and can produce an oops or panic, taking the client system or critical kernel functionality out of service." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
