Descriptions

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

accel/ivpu: Fix deadlock in context_xa

ivpu_device->context_xa is locked both in kernel thread and IRQ context.
It requires XA_FLAGS_LOCK_IRQ flag to be passed during initialization
otherwise the lock could be acquired from a thread and interrupted by
an IRQ that locks it for the second time causing the deadlock.

This deadlock was reported by lockdep and observed in internal tests.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: accel/ivpu: corrige el punto muerto en context_xa ivpu_device->context_xa está bloqueado tanto en el subproceso del kernel como en el contexto IRQ. Requiere que se pase el indicador XA_FLAGS_LOCK_IRQ durante la inicialización; de lo contrario, el bloqueo podría adquirirse de un subproceso e interrumpirse mediante una IRQ que lo bloquee por segunda vez, provocando el punto muerto. Este punto muerto fue informado por lockdep y observado en pruebas internas.
