CVE-2026-43035
Description
AI Translation Available
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.
