GHSA-J66F-JC3V-93VP

Vulnerability from github – Published: 2024-02-21 15:30 – Updated: 2024-03-15 15:30

Details

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.

Severity ?

7.8 (High)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
