Official Description
In the Linux kernel, the following vulnerability has been resolved:
platform/chrome: cros_ec_typec: Init mutex in Thunderbolt registration
cros_typec_register_thunderbolt() missed initializing the `adata->lock`
mutex. This leads to a NULL dereference when the mutex is later
acquired (e.g. in cros_typec_altmode_work()).
Initialize the mutex in cros_typec_register_thunderbolt() to fix the
issue.
Technical Analysis
CVE-2026-46134 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
