  "details": "In the Linux kernel, the following vulnerability has been resolved:  net: sched: cls_api: fix tc_chain_fill_node to initialize tcm_info to zero to prevent an info-leak  When building netlink messages, tc_chain_fill_node() never initializes the tcm_info field of struct tcmsg. Since the allocation is not zeroed, kernel heap memory is leaked to userspace through this 4-byte field.  The fix simply zeroes tcm_info alongside the other fields that are already initialized.",
