A malicious/compromised NFS server or an on-path attacker tampering with unprotected AUTH_SYS NFS traffic triggers it remotely.\nAC:L - The server fully controls the response bitmap and can set FATTR4_WORD2_MDSTHRESHOLD on any reply, so the write through the uninitialized pointer happens reliably on the next attribute revalidation. The stale heap contents are groomable because the attacker can induce repeated nfs_fattr kmalloc/kfree cycles via NFS operations, so no condition lies outside attacker influence.\nPR:N - No credentials or privileges on the victim client are required; the client accepts and decodes the server's reply bitmap without validating it against what it requested, and without authenticating the response. The attack is executed from the server/network side.\nUI:N - On an existing NFSv4 mount, attribute revalidation is driven automatically by any path lookup, stat, or cache expiry from any process, including background activity. No specific victim action is needed for the malicious reply to be decoded.\nS:U - The memory corruption occurs in the NFS client's kernel address space and is confined to the same security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - Use of the uninitialized pointer plus a controlled kernel write primitive allows an attacker to corrupt adjacent kernel structures and leverage the corruption for arbitrary kernel memory disclosure. Per kernel guidance, memory corruption exploitable for info disclosure is High.\nI:H - decode_first_threshold_item4() writes four attacker-supplied 64-bit values plus a 32-bit l_type through an uninitialized, heap-groomable kernel pointer \u2014 an ~40-byte arbitrary write with fully controlled contents, sufficient for control-flow hijack and kernel code execution.\nA:H - Writing through a garbage pointer will typically fault on an unmapped or read-only kernel address, producing an oops or panic on the NFS client, and it is triggerable repeatedly by the remote server."}]}], "affected":
