Code Review
This pull request updates several OpenTelemetry dependencies in go.mod from version v1.42.0 to v1.43.0. A review comment identifies that the update is incomplete because the OTLP exporters (otlpmetrichttp and otlptracehttp) were left at v1.42.0. These should be updated to v1.43.0 to maintain version consistency and to apply security fixes that mitigate potential memory exhaustion vulnerabilities.

Summary
The fix for GHSA-9h8m-3fm2-qjrq (CVE-2026-24051) changed the Darwin
ioregcommand to use an absolute path but left the BSDkenvcommand using a bare name, allowing the same PATH hijacking attack on BSD and Solaris platforms.Root Cause
sdk/resource/host_id.goline 42:Compare with the fixed Darwin path at line 58:
The
execCommandhelper atsdk/resource/host_id_exec.gousesexec.Command(name, arg...)which searches$PATHwhen the command name contains no path separator.Affected platforms (per build tag in
host_id_bsd.go:4): DragonFly BSD, FreeBSD, NetBSD, OpenBSD, Solaris.The
kenvpath is reached when/etc/hostiddoes not exist (line 38-40), which is common on FreeBSD systems.Attack
