CVE-2026-46134
Description
A flaw was found in the Linux kernel's cros_ec_typec component. This vulnerability occurs because a mutex, a mechanism used to prevent simultaneous access to shared resources, was not properly initialized during Thunderbolt registration. This oversight can lead to a NULL dereference, potentially causing system instability or a denial of service (DoS) for affected systems.
Understanding the Weakness (CWE)

Availability
Technical Impact: DoS: Crash, Exit, or Restart
The uninitialized resource may contain values that cause program flow to change in ways that the programmer did not intend.
