How to fix?

Upgrade Wolfi k3s to version 1.29.2-r1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream k3s package and not the k3s package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

When parsing a multipart form (either explicitly with Request.ParseMultipartForm or implicitly with Request.FormValue, Request.PostFormValue, or Request.FormFile), limits on the total size of the parsed form were not applied to the memory consumed while reading a single form line. This permits a maliciously crafted input containing very long lines to cause allocation of arbitrarily large amounts of memory, potentially leading to memory exhaustion. With fix, the ParseMultipartForm function now correctly limits the maximum size of form lines.
