Description

In the Linux kernel, the following vulnerability has been resolved: fs: init flags_valid before calling vfs_fileattr_get syzbot reported a uninit-value bug in [1]. Similar to the "*get" context where the kernel's internal file_kattr structure is initialized before calling vfs_fileattr_get(), we should use the same mechanism when using fa.
