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().
