In the Linux kernel, the following vulnerability has been resolved: sysctl: Fix out of bounds access for empty sysctl registers When registering tables to the sysctl subsystem there is a check to see if header is a permanently empty directory (used for mounts). This check evaluates the first element of the ctltable. This results in an out of bounds evaluation when registering empty directories. The function registersysctlmountpoint now passes a ctltable of size 1 instead of size 0. It now relies solely on the type to identify a permanently empty register. Make sure that the ctltable has at least one element before testing for permanent emptiness.
