CVE-2024-35960 is a Linux kernel flaw in the net/mlx5 flow-steering rule-management logic. Before the fix, add_rule_fg() linked a newly created rule into the rule tree only when its reference count was one. During create_flow_handle(), an identical newly created rule could be referenced again while the same flow handle was being created. The rule could therefore have a reference count of two while remaining unlinked, with NULL parent and root pointers. When the corresponding flow group is deleted, del_sw_hw_rule() dereferences the assumed non-NULL parent pointer and crashes the kernel. The corrective change links new parentless rules into the tree and initializes them properly.

A Linux kernel net/mlx5 flow-steering rule-management vulnerability. Improper linking of newly created rules into the flow-steering tree can cause a kernel crash when an affected flow group is deleted. Google COS packages sys-kernel/csql-kernel-6_1 and sys-kernel/lakitu-kernel-6_1 are affected; version 18244.85.5 or later remediates it.
