CVE-2023-54238

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mlx5: fix skb leak while fifo resync and push<br /> <br /> During ptp resync operation SKBs were poped from the fifo but were never<br /> freed neither by napi_consume nor by dev_kfree_skb_any. Add call to<br /> napi_consume_skb to properly free SKBs.<br /> <br /> Another leak was happening because mlx5e_skb_fifo_has_room() had an error<br /> in the check. Comparing free running counters works well unless C promotes<br /> the types to something wider than the counter. In this case counters are<br /> u16 but the result of the substraction is promouted to int and it causes<br /> wrong result (negative value) of the check when producer have already<br /> overlapped but consumer haven&amp;#39;t yet. Explicit cast to u16 fixes the issue.
