  "title": "dmaengine: fsl-edma: tracing: no ptr dereference during log output",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  dmaengine: fsl-edma: tracing: no ptr dereference during log output  The fsl edma events store a pointer to a struct fsl_edma_engine in the ringbuffer and dereference it when a log entry is printed. At this time, the pointer may no longer be valid.  Event injection can be used to trigger a crash:  $ cd /sys/kernel/tracing $ echo \u0027value = 0\u0027 \u003E events/fsl_edma/edma_writeb/inject $ cat trace  The log output needs only edma-\u003Emembase. Add a membase field at the end of the event and use the new field for log output. Keep the existing fields for backward compatibility.",
