Description OSIDB Bzimport 2025-10-04 08:02:50 UTC 
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.
