Affected: Go standard library crypto/x509

Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts that will be printed out. Furthermore, the error string is constructed by repeated string concatenation, leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in excessive resource consumption.

 https://cve.radiocsirt.org/vuln/ghsa-hfvc-g4fc-pqhx GHSA-hfvc-g4fc-pqhx — opentelemetry-go: BSD kenv command not using absolute path enables PATH hijacking 2026-10-16T02:38:05.184597+00:00

Affected: Go: go.opentelemetry.io/otel/sdk

## Summary

The fix for GHSA-9h8m-3fm2-qjrq (CVE-2026-24051) changed the Darwin `ioreg` command to use an absolute path but left the BSD `kenv` command using a bare name, allowing the same PATH hijacking attack on BSD and Solaris platforms.

## Root Cause

`sdk/resource/host_id.go` line 42:

if result, err := r.execCommand("kenv", "-q", "smbios.system.uuid"); err == nil {

Compare with the fixed Darwin path at line 58:

result, err := r.execCommand("/usr/sbin/ioreg", "-rd1", "-c", "IOPlatformExpertDevice")

The `execCommand` helper at `sdk/resource/host_id_exec.go` uses `exec.Command(name, arg...)` which searches `$PATH` when 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 `kenv` path is reached when `/etc/hostid` does not exist (line 38-40), which is common on FreeBSD systems.

## Attack

1. Attacker has local access to a system running a Go application that imports `go.opentelemetry.io/otel/sdk` 2. Attacker places a malicious `kenv` binary earlier in `$PATH` 3. Application initializes OpenTelemetry resource detection at startup 4. `hostIDReaderBSD.read()` calls `exec.Command("kenv", ...)` which resolves to the malicious binary 5. Arbitrary code executes in the context of the application

Same attack vector and impact as CVE-2026-24051.

## Suggested Fix

Use the absolute path:

if result, err := r.execCommand("/bin/kenv", "-q", "smbios.system.uuid"); e…
