OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, the per-CPU message-buffer fallback path uses a 256-byte backup buffer but preserves the original payload size, which can be up to 8KB. If a CPU mismatch occurs, OBI can read beyond the fallback buffer and leak adjacent memory into telemetry. This issue has been patched in version 0.9.0.

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:22032-1 advisory.

    - CVE-2026-2303: go.mongodb.org/mongo-driver: mongo-go-driver has Heap Out-of-Bounds Read in GSSAPI Error     Handling       (bsc#1269861).
    - CVE-2026-37236: github.com/grpc-ecosystem/grpc-gateway/v2/runtime: client can override the HTTP method     of a POST       request through the X-HTTP-Method-Override header and bypass established access control (bsc#1277996).
    - CVE-2026-41178: go.opentelemetry.io/otel/baggage: no rejection of raw-length headers in baggage parsing     allows for DoS       via oversized inputs (bsc#1276742).

    - CVE-2026-45683: go.opentelemetry.io/obi: Java TLS ioctl kprobe allows a user to point OBI at kernel     memory and cause       that memory to be copied into telemetry (bsc#1267486).
    - CVE-2026-45684: go.opentelemetry.io/obi: log enricher mishandled `writev` buffers and allows multi-     segment calls to       read and overwrite memory beyond the first segment (bsc#1267487).
    - CVE-2026-46600: golang.org/x/net/dns/dnsmessage: Parsing an invalid SVCB or HTTPS RR can panic when the     size of a       parameter value overflows the message buffer (bsc#1272418).

    - CVE-2026-75889: arbitrary file reads due to the `prometheus.operator.servicemonitors` component allowing     users who can       modify `ServiceMonitor` resources in a watched namespace to specify an arbitrary local file through     `bearerTokenFile`       (bsc#1277429).
    - CVE-2026-81521: go.mongodb.org/mongo-driver: MongoDB Go Driver: Write redirection via unvalidated     database name in       Client.BulkWrite (bsc#1278693).

    Changes for alloy:

    Update to version 1.19.2:

     * Remove withdrawn lib/pq CVEs from govulncheck
     * Add backticks to component name in generated doc output
     * BREAKING CHANGE: prometheus.operator.servicemonitors now      rejects endpoints that reference local files by default. Set      allow_arbitrary_file_access = true to preserve previous      behavior.
     * prometheus.enrich: Support multi-label matching
     * prometheus.relabel: Add opt-in TTL cache mode
     * telemetry: Add new metrics for graph connections and      pyroscope forwarded entries
     * database_observability: Exclude system schemas from MySQL      health checks and redact query text in explain_plans
     * Add nop receiver to OTel Engine
     * Backport dependency upgrades to address GO-2026-6061
