Upgrade github.com/moby/buildkit/solver/llbsolver/ops to version 0.31.2 or higher.
Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference through the LLB solver and llbsolver operation handling in solver/llbsolver/ops and solver/llbsolver/vertex.go. An attacker can crash the BuildKit daemon by supplying a malicious frontend or LLB definition with negative or out-of-range op input indices, or by omitting required diff inputs, causing a slice-index panic or nil pointer dereference during load and cache-key computation.
