Linux Distros Unpatched Vulnerability : CVE-2026-45404

medium Nessus Plugin ID 340711

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - OpenTelemetry-Go is the Go implementation of OpenTelemetry. From version 0.11.0 through 1.44.0, the OpenTracing bridge's bridgeSpan contains an unsynchronized extraBaggageItems map which can cause a panic.
 Because Go maps are not safe for concurrent read/write access, concurrent SetBaggageItem and correlation.MapFromContext calls on the same hooked bridgeSpan can trigger a fatal runtime errorsuch as concurrent map read and map write or concurrent map iteration and map writeterminating the process and causing denial of service. This issue is fixed in version 1.45.0. (CVE-2026-45404)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
