Description SMASH SMASH 2024-02-22 14:17:40 UTC 
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.

Hi Michal,

Because this is a issue for net/tls. Could you please help to handle it?

If this is not in your area, just reset bug assigner to kernel-bugs@suse.de. Kernel Security Sentinel will find other expert.

Thanks a lot!
