Descriptions

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.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: tls: obtenga referencia de psock después de tomar rxlock para evitar fugas. Al inicio de tls_sw_recvmsg, tomamos una referencia en psock y luego llamamos a tls_rx_reader_lock. Si eso falla, volvemos directamente sin liberar la referencia. En lugar de agregar una nueva etiqueta, simplemente tome la referencia después de que el bloqueo se haya realizado correctamente, ya que no la necesitamos antes.
