CVE-2025-38120

Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: The issue is related to the netfilter in the Linux kernel, specifically with the nf set pipapo avx2 function. The problem occurs when the first field does not cover the entire start map, causing bits to leak into the next match round map. An initial fix was incomplete, only addressing the generic C implementation. A follow-up patch added a test case to nft concat range.sh.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
