This seems to fix the fuzz issue, I'll add the patch to my queue for autobuilder testing.
For future patches there is no need for [meta] in the subject line. Just something like "[OE-core][kirkstone][PATCH] curl: Add fix for CVE-2023-23916" is perfect. Also when you are sending multiple versions of the patch use something like: "[OE-core][kirkstone][PATCH v2] curl: Add fix for CVE-2023-23916" and include a comment after the line with three dashes describing the changes in this version. See below for example.
