CVE-2026-72006
Overview
CVE-2026-72006 is a known-severity vulnerability. It was published on August 15, 2026.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: free mlx5_st_idx_data on final dealloc
Workloads that repeatedly allocate and release mkeys carrying TPH
steering-tag hints (e.g. churning RDMA MRs) leak one
struct mlx5_st_idx_data per cycle; kmemleak flags it as unreferenced
and the kmalloc slab grows over time.
When the last reference to an ST table entry is dropped,
mlx5_st_dealloc_index() removed the entry from idx_xa but the backing
mlx5_st_idx_data allocation was never freed.
Free idx_data after the xa_erase() so the lifetime of the bookkeeping
struct matches the lifetime of the ST entry it tracks.
