MEMORANDUM **

California state prisoner Darnell Garcia appeals pro se from the district court’s judgment dismissing his habeas petition. We have jurisdiction under 28 U.S.C. § 1291, and we affirm.

Garcia contends that he has served more time than is necessary because the district *632 court did not modify his presentence investigation report (“PSR”), or order a supplemental report, to reflect the sentence reduction that he received on direct appeal. Garcia’s petition challenges the legality, rather than the execution, of his sentence, and his claims do not qualify for the savings clause of 28 U.S.C. § 2255, whereby a prisoner may challenge his sentence in a 28 U.S.C. § 2241 petition. We therefore construe this appeal as a successive § 2255 motion, which must be certified by this court before it can be presented to the district court. See Harrison v. Ollison, 519 F.3d 952, 956, 959-960 (9th Cir. 2008). The district court therefore lacked jurisdiction to consider this claim. See 28 U.S.C. § 2244(b); see also United States v. Allen, 157 F.3d 661, 664 (9th Cir. 1998).

We construe Garcia’s notice of appeal as a request for a certificate of appealability on the issue of whether his motion was properly dismissed as second or successive without authorization. So construed, the motion is denied. See 9th Cir. R. 22-1(d); see also Slack v. McDaniel, 529 U.S. 473, 483-85, 120 S.Ct. 1595, 146 L.Ed.2d 542 (2000).

AFFIRMED.
