CyberRota Analysis

AI-Generated

The vulnerability affects systems using the ptrace(PT_SC_REMOTE) system call, where the kernel incorrectly logs the return value of an internal setup function instead of the actual result of the executed system call. This misrepresentation can lead to audit records indicating successful operations despite failures, potentially allowing attackers with debugging capabilities to create misleading audit trails and evade detection by Intrusion Detection Systems (IDS). Organizations relying on audit logs for security monitoring should prioritize addressing this issue to maintain the integrity of their auditing processes.

Original NVD Description

When auditing a system call executed via ptrace(PT_SC_REMOTE), the kernel passed the return value of an internal setup function to AUDIT_SYSCALL_EXIT() rather than the actual result of the executed system call. As a result, committed audit records for system calls which returned an error do not reflect the true outcome of the operation. That is, they indicate that the operation succeeded when it in fact failed. Audit records for system calls executed via ptrace(PT_SC_REMOTE) may show an incorrect error status. An attacker with the ability to debug a process could use this to produce misleading audit trails, potentially undermining audit-based Intrusion Detection Systems (IDS).
