CVE-2023-53684 Details
Description
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.
A vulnerability exists in the Linux kernel's XFRM subsystem, specifically in the handling of algorithms and encapsulation templates when data is copied to user space. This issue can lead to the unintentional exposure of sensitive data, as padding in data structures may contain random, potentially sensitive information that should not be transmitted to user space. The vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The specific commits that fix this issue are available in the Linux kernel stable tree.
