CVSS 3.0
5.5 mediumCVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2017-12193
Medium (5.5) in linux linux kernel. EPSS 0.5% chance of exploitation in the next 30 days.
The assoc_array_insert_into_terminal_node function in lib/assoc_array.c in the Linux kernel before 4.13.11 mishandles node splitting, which allows local users to cause a denial of service (NULL pointer dereference and panic) via a crafted application, as demonstrated by the keyring key type, and key addition and link creation operations.
