Description
In the Linux kernel, the following vulnerability has been resolved:
ch_ktls: Fix kernel panic
Taking page refcount is not ideal and causes kernel panic
sometimes. It's better to take tx_ctx lock for the complete
skb transmit, to avoid page cleanup if ACK received in middle.
Affected configurations
• linux linux kernel (>= 5.7.0 < 5.10.32)
• linux linux kernel (>= 5.11.0 < 5.11.16)
