CVE-2017-12193 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.46% chance of exploitation in the next 30 days.
