AnalysisCVE.org

In the Linux kernel, the following vulnerability has been resolved:

drm/amdkfd: Unwind debug trap enable on copy_to_user failure

If kfd_dbg_trap_enable() fails while copying runtime_info to userspace, it had already activated the trap, set debug_trap_enabled, taken an extra process reference, and opened the debug event file. Return -EFAULT without unwinding that state, leaving inconsistent trap state and a refcount imbalance that could break later DISABLE/ENABLE.

On copy_to_user failure, deactivate the trap and undo the rest of the enable setup before returning.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
