CVE-2026-48496: CWE-770: Allocation of Resources Without Limits or Throttling in open-telemetry opentelemetry-ebpf-profiler
OpenTelemetry eBPF Profiler is a production-scale agent for profiling applications across multiple programming languages. Starting in version 0.0.202527 and prior to version 0.0.202622, an unprivileged process can cause the profiler to open a nonregular mapping file, such as a FIFO, and block indefinitely, preventing further ELF analysis and causing a denial of service. Version 0.0.202622 contains a patch. No known workarounds are available.
AI Analysis
Technical Summary
CVE-2026-48496 is a CWE-770 vulnerability in the open-telemetry opentelemetry-ebpf-profiler component. The flaw allows an unprivileged process to trigger the profiler to open a nonregular mapping file such as a FIFO, causing the profiler to block indefinitely and preventing further ELF analysis. This results in a denial of service condition. The vulnerability affects versions >=0.0.202527 and <0.0.202622. Version 0.0.202622 contains a patch that addresses this issue.
Potential Impact
The vulnerability causes a denial of service by blocking the profiler indefinitely, which disrupts its ability to perform ELF analysis. There is no impact on confidentiality or integrity. The CVSS v3.1 score is 6.2 (medium severity) with attack vector local, low attack complexity, no privileges required, no user interaction, and impact limited to availability.
Mitigation Recommendations
Upgrade to version 0.0.202622 or later, which contains the official patch for this vulnerability. No known workarounds are available.
