In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix sd_ndr.data memory leak in ksmbd_vfs_set_sd_xattr ndr_encode_v4_ntacl() allocates sd_ndr.data via kzalloc() at entry. If any subsequent ndr_write_*() call returns error during encoding, the allocated sd_ndr.data won't be freed and causes memory leak. Move kfree(sd_ndr.data) into out label to ensure the buffer gets released on all success and error return paths.
