CVE-2023-53013

  3. CVE-2023-53013
In the Linux kernel, the following vulnerability has been resolved: ptdma: pt_core_execute_cmd() should use spinlock The interrupt handler (pt_core_irq_handler()) of the ptdma driver can be called from interrupt context. The code flow in this function can lead down to pt_core_execute_cmd() which will attempt to grab a mutex, which is not appropriate in interrupt context and ultimately leads to a kernel panic. The fix here changes this mutex to a spinlock, which has been verified to resolve the issue.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ptdma: pt_core_execute_cmd() debería usar un bloqueo de giro. El manejador de interrupciones (pt_core_irq_handler()) del controlador ptdma puede llamarse desde el contexto de interrupción. El flujo de código en esta función puede derivar en pt_core_execute_cmd(), que intentará obtener un mutex, lo cual no es apropiado en el contexto de interrupción y, en última instancia, provoca un pánico del kernel. Esta corrección convierte este mutex en un bloqueo de giro, lo cual se ha verificado para resolver el problema.
