CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: dm raid: fix address sanitizer warning in raid_resume There is a KASAN warning in raid_resume when running the lvm test lvconvert-raid.sh. The reason for the warning is that mddev->raid_disks is greater than rs->raid_disks, so the loop touches one entry beyond the allocated length.

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2022-50085 since 06/18/2025. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 242100 (SUSE SLES15 Security Update : kernel (SUSE-SU-2025:02308-1)), which helps to determine the existence of the flaw in a target environment.
