CVE-2018-20449
The hidma_chan_stats function in drivers/dma/qcom/hidma_dbg.c in the Linux kernel 4.14.90 allows local users to obtain sensitive address information by reading "callback=" lines in a debugfs file.
Does this matter?
Lower severity and a low EPSS score (0.42%). Track it; it rarely justifies an emergency change on its own.
