Recommendation: Monitor — no exploitation signal at the moment.

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.

Affected products

n/a · Linux kernel since 3.13 up to 4.14 (not including)
