Last modified

CVE-2015-2666 is a vulnerability of currently unknown severity. Stack-based buffer overflow in the get_matching_model_microcode function in arch/x86/kernel/cpu/microcode/intel_early.c in the Linux kernel before 4.0 allows context-dependent attackers to gain privileges by constructing a crafted microcode header and leveraging root privileges for write access to the initrd.. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
