Description : In the Linux kernel, the following vulnerability has been resolved:

hfs: fix potential use after free in hfs_correct_next_unused_CNID()

This code calls hfs_bnode_put(node) which drops the refcount and then
dreferences “node” on the next line. It’s only safe to use “node”
when we’re holding a reference so flip these two lines around.

Severity: 0.0 | NA
