What access does an attacker need to exploit this issue?
The CVSS vector indicates local access and low privileges are required. No user interaction is required.
2
What is the security impact?
A false positive involving a detached fanotify mark on an unrelated group can bypass a permission check. The CVSS assessment rates confidentiality and integrity impact as high, with no availability impact.
3
Which systems are identified as affected?
The affected software list includes the Linux kernel and Microsoft azl3 kernel 6.6.139.1-1. The provided data does not identify affected upstream kernel version ranges or default configuration conditions.
