FKIE_CVE-2023-53684

Vulnerability from fkie_nvd - Published: 2025-10-07 16:15 - Updated: 2026-02-26 23:10
Summary
In the Linux kernel, the following vulnerability has been resolved: xfrm: Zero padding when dumping algos and encap When copying data to user-space we should ensure that only valid data is copied over. Padding in structures may be filled with random (possibly sensitve) data and should never be given directly to user-space. This patch fixes the copying of xfrm algorithms and the encap template in xfrm_user so that padding is zeroed.
