title: Kernel: xfrm: out-of-bounds read of xfrma_mtimer_thresh nlattr
description: A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to cause a 4 byte out-of-bounds read of XFRMA_MTIMER_THRESH when parsing netlink attributes, leading to potential leakage of sensitive heap data to userspace.
problem types: Out-of-bounds Read
