  "details": "In the Linux kernel, the following vulnerability has been resolved:  ksmbd: Fix acl.sd_buf memory leak and invalid sd_size error handling  1. When ndr_decode_v4_ntacl() fails, the code jumped to free_n_data    which only freed n.data, skipping kfree(acl.sd_buf) and leaking    the buffer. Zero-initialize struct xattr_ntacl acl, reorder error    labels to out_free to release acl.sd_buf on all error paths.  2. if (acl.sd_size \u003c sizeof(struct smb_ntsd)) is true, original code    returned success without freeing sd_buf and left stale *pntsd.    Set rc = -EINVAL before jumping to out_free to return error code and    free buffer.",
