  3. CVE-2024-46717
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: SHAMPO, Fix incorrect page release Under the following conditions: 1) No skb created yet 2) header_size == 0 (no SHAMPO header) 3) header_index + 1 % MLX5E_SHAMPO_WQ_HEADER_PER_PAGE == 0 (this is the last page fragment of a SHAMPO header page) a new skb is formed with a page that is NOT a SHAMPO header page (it is a regular data page). Further down in the same function (mlx5e_handle_rx_cqe_mpwrq_shampo()), a SHAMPO header page from header_index is released. This is wrong and it leads to SHAMPO header pages being released more than once.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/mlx5e: SHAMPO, Corregir liberación de página incorrecta Bajo las siguientes condiciones: 1) No se ha creado ningún skb todavía 2) header_size == 0 (no hay encabezado SHAMPO) 3) header_index + 1 % MLX5E_SHAMPO_WQ_HEADER_PER_PAGE == 0 (este es el último fragmento de página de una página de encabezado SHAMPO) se forma un nuevo skb con una página que NO es una página de encabezado SHAMPO (es una página de datos normal). Más abajo en la misma función (mlx5e_handle_rx_cqe_mpwrq_shampo()), se libera una página de encabezado SHAMPO de header_index. Esto es incorrecto y lleva a que las páginas de encabezado SHAMPO se liberen más de una vez.
