NVD Description

Note: Versions mentioned in the description apply only to the upstream efs-utils-for-aws-csi-driver package and not the efs-utils-for-aws-csi-driver package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

RustCrypto CMOV provides conditional move CPU intrinsics which are guaranteed on major platforms to execute in constant-time and not be rewritten as branches by the compiler. From 0.1.1 until 0.5.4, the aarch64 implementations of Cmov and CmovEq in cmov/src/backends/aarch64.rs assume high bits are zero-extended when loading values smaller than a register, so set high bits such as [8..] in a Cmov selector or [16..] of self or other in the u16 and i16 CmovEq implementations can cause left.cmovz(&right, condition) to produce incorrect output. This issue is fixed in version 0.5.4.
