CVE-2015-3693 is a vulnerability of currently unknown severity. Apple Mac EFI before 2015-001, as used in OS X before 10.10.4 and other products, does not properly set refresh rates for DDR3 RAM, which might make it easier for remote attackers to conduct row-hammer attacks, and consequently gain privileges or cause a denial of service (memory corruption), by triggering certain patterns of access to memory locations.. EPSS estimates a 7.66% chance of exploitation in the next 30 days.
