CVE-2025-38432

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

Description A flaw exists in the Linux kernel's netpoll functionality related to UDP checksum handling. A commit removed the initialization of the UDP checksum field, leading to incorrect checksumming and broken IPv6 transmission when using netpoll. The udph->check field requires initialization before the csum ipv6 magic() function is called.

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