The tls_decrypt_sg() function doesn't take references on the pages from clear_skb, so the put_page() in tls_decrypt_done() releases them and a use-after-free can be triggered in process_rx_list when trying to read from the partially-read skb. This issue could lead to a denial of service condition or code execution." ],

Red Hat Enterprise Linux 8 is not affected as it did not include the upstream commit that introduced this flaw (fd31f39 \"tls: rx: decrypt into a fresh skb\").",
