Detection & IOCsextracted from sources · hover to see the quote

  • Target component is the Windows Common Log File System (CLFS) Driver — monitor for anomalous interactions with clfs.sys or CLFS log files that may indicate out-of-bounds read exploitation attempts.
  • Focus privilege-escalation detection on processes transitioning from Medium Integrity Level to High Integrity Level, which is the specific privilege gain path for this vulnerability.
  • ·Microsoft rates exploitation as 'More Likely' for the latest software release, despite no confirmed in-the-wild exploitation at time of disclosure — prioritise patching accordingly.
  • ·CISA has added this CVE to the Known Exploited Vulnerabilities catalog with a remediation due date of 2026-04-27; apply vendor mitigations or discontinue use if mitigations are unavailable.
