Summary
In the Linux kernel, the following vulnerability has been resolved: lib/generic-radix-tree.c: Don't overflow in peek() When we started spreading new inode numbers throughout most of the 64 bit inode space, that triggered some corner case bugs, in particular some integer overflows related to the radix tree code.
