Overview
CVE-2022-50642 is a known-severity vulnerability. It was published on December 9, 2025.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
platform/chrome: cros_ec_typec: zero out stale pointers
`cros_typec_get_switch_handles` allocates four pointers when obtaining
type-c switch handles. These pointers are all freed if failing to obtain
any of them; therefore, pointers in `port` become stale. The stale
pointers eventually cause use-after-free or double free in later code
paths. Zeroing out all pointer fields after freeing to eliminate these
stale pointers.
