# CVE-2026-72039: bnx2x: fix potential memory leak in bnx2x_alloc_mem_bp()

Status: published. Published: 2026-08-15. Updated: 2026-11-06.

In the Linux kernel, the following vulnerability has been resolved:

bnx2x: fix potential memory leak in bnx2x_alloc_mem_bp()

If the allocation of fp[i].tpa_info fails, the error path will not free
the struct bnx2x_fastpath allocated earlier, as it is not linked to the
bp structure yet. Fix that by linking it immediately after allocation.
