CVE-2024-35908 Information

Description

In the Linux kernel the following vulnerability has been resolved:

tls: get psock ref after taking rxlock to avoid leak

At the start of tls_sw_recvmsg we take a reference on the psock and then call tls_rx_reader_lock. If that fails we return directly without releasing the reference.

Instead of adding a new label just take the reference after locking has succeeded since we don’t need it before.
