Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: tracing/probes: Remove WARN_ON_ONCE from parse_btf_arg Sashiko found that user can cause this WARN_ON_ONCE() easily with adding a kprobe event based on a raw address with BTF parameter. Since this is not an unexpected condition, remove the WARN_ON_ONCE().

Executive Summary

This vulnerability in the Linux kernel involves a WARN_ON_ONCE() call in the tracing/probes subsystem. It occurs when a user adds a kprobe event based on a raw address with a BTF parameter, which triggers the warning unnecessarily. The issue was resolved by removing the WARN_ON_ONCE() since the condition is not unexpected.

Detection Guidance

This vulnerability is related to the Linux kernel's tracing/probes subsystem. Detection requires checking kernel logs for WARN_ON_ONCE() messages related to parse_btf_arg. Use commands like dmesg | grep -i 'WARN_ON_ONCE' or journalctl -k | grep -i 'parse_btf_arg' to identify such events.

Impact Analysis

This vulnerability may cause unnecessary warnings in the kernel logs when users interact with kprobe events using raw addresses with BTF parameters. It does not directly lead to security risks but could affect system stability or debugging processes due to excessive warnings.

Compliance Impact

This vulnerability does not directly affect compliance with standards like GDPR or HIPAA. It is a kernel-level issue related to tracing/probes functionality, specifically involving a WARN_ON_ONCE() condition that can be triggered by user actions. There is no indication of data exposure or security impact that would compromise compliance requirements.

Mitigation Strategies

Update your Linux kernel to the latest stable version that includes the fix for this issue. Monitor kernel logs for any related warnings after applying the update.
