In the Linux kernel, the following vulnerability has been resolved: net:
tls: fix use-after-free with partial reads and async decrypt tls_decrypt_sg
doesn’t take a reference on the pages from clear_skb, so the put_page() in
tls_decrypt_done releases them, and we trigger a use-after-free in
process_rx_list when we try to read from the partially-read skb.
