About vulnerability

In the Linux kernel, the following vulnerability has been resolved:

tty: vcc: zero-initialize control packet in vcc_send_ctl()

The stack-allocated struct vio_vcc pkt was partially initialized, leaving the tag.stype_env field uninitialized before being sent via ldc_write(), potentially leaking kernel stack data to the LDC peer.
