Summary
In the Linux kernel, the following vulnerability has been resolved: nfs: Fix KMSAN warning in decode_getfattr_attrs() Fix the following KMSAN warning: CPU: 1 UID: 0 PID: 7651 Comm: cp Tainted: G B Tainted: [B]=BAD_PAGE Hardware name: QEMU Standard PC (Q35 + ICH9, 2009) ===================================================== ===================================================== BUG: KMSAN: uninit-value in decode_getfattr_attrs+0x2d6d/0x2f90 decode_getfattr_attrs+0x2d6d/0x2f90 decode_getfattr_generic+0x806/0xb00 nfs4_xdr_dec_getattr+0x1de/0x240 rpcauth_unwrap_resp_decode+0xab/0x100 rpcauth_unwrap_resp+0x95/0xc0 call_decode+0x4ff/0xb50 __rpc_execute+0x57b/0x19d0 rpc_execute+0x368/0x5e0 rpc_run_task+0xcfe/0xee0 nfs4_proc_getattr+0x5b5/0x990 __nfs_revalidate_inode+0x477/0xd00 nfs_access_get_cached+0x1021/0x1cc0 nfs_do_access+0x9f/0xae0 nfs_permission+0x1e4/0x8c0 inode_permission+0x356/0x6c0 link_path_walk+0x958/0x1330 path_lookupat+0xce/0x6b0 filename_lookup+0x23e/0x770 vfs_statx+0xe7/0x970 vfs_fstatat+0x1f2/0x2c0 __se_sys_newfstatat+0x67/0x880 __x64_sys_newfstatat+0xbd/0x120 x64_sys_call+0x1826/0x3cf0 do_syscall_64+0xd0/0x1b0 entry_SYSCALL_64_after_hwframe+0x77/0x7f The KMSAN warning is triggered in decode_getfattr_attrs(), when calling decode_attr_mdsthreshold(). It appears that fattr->mdsthreshold is not initialized. Fix the issue by initializing fattr->mdsthreshold to NULL in nfs_fattr_init().

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\u0027s 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\u0027s 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."
