CVE-2017-17052: Linux Kernel

High severity, CVSS 7.8. EPSS: 0.4% chance of exploitation in the next 30 days.

The mm_init function in kernel/fork.c in the Linux kernel before 4.12.10 does not clear the ->exe_file member of a new process's mm_struct, allowing a local attacker to achieve a use-after-free or possibly have unspecified other impact by running a specially crafted program.

Affected products

• Linux Linux Kernel: from 4.7, before 4.9.46 (fixed in 4.9.46); from 4.10, before 4.12.10 (fixed in 4.12.10)
