CVE-2022-50642

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> platform/chrome: cros_ec_typec: zero out stale pointers<br /> <br /> `cros_typec_get_switch_handles` allocates four pointers when obtaining<br /> type-c switch handles. These pointers are all freed if failing to obtain<br /> any of them; therefore, pointers in `port` become stale. The stale<br /> pointers eventually cause use-after-free or double free in later code<br /> paths. Zeroing out all pointer fields after freeing to eliminate these<br /> stale pointers.
