## Overview

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.

## Affected

- `linux_kernel >= 6.0, < 6.1.79`
- `linux_kernel >= 6.2.0, < 6.6.18`
- `linux_kernel >= 6.7.0, < 6.7.6`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.6`
