CVE-2025-39934

Estado: AnalizadaMedia (5.5)—

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

drm: bridge: anx7625: Fix NULL pointer dereference with early IRQ

If the interrupt occurs before resource initialization is complete, the interrupt handler/worker may access uninitialized data such as the I2C tcpc_client device, potentially leading to NULL pointer dereference.
