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

Description A flaw exists in the Linux kernel related to the handling of xfrm algorithms and encap templates when copying data to user-space. Padding within structures may contain random or sensitive data, which could be inadvertently exposed to user-space. The issue arises from insufficient zero padding during the dumping of algorithms and encapsulation templates in the xfrm subsystem. This could lead to the disclosure of potentially sensitive information.

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