CVE-2018-20509
The print_binder_ref_olocked function in drivers/android/binder.c in the Linux kernel 4.14.90 allows local users to obtain sensitive address information by reading " ref *desc *node" lines in a debugfs file.
Does this matter?
Lower severity and a low EPSS score (0.37%). Track it; it rarely justifies an emergency change on its own.
