CVE-2026-23257

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

Description The Linux kernel contains an issue within the net/liquidio module related to memory management during device setup and cleanup. Specifically, a flaw exists in the setup nic devices() function where the cleanup loop incorrectly skips failing indices, leading to a memory leak. The issue arises because the loop iterates incorrectly after encountering a failure during device initialization. The problem was identified through code review and addressed by modifying the cleanup loop to iterate from the current index down to zero and by decrementing i in the devlink alloc failure path.

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