- Summary
- hfs: fix potential use after free in hfs_correct_next_unused_CNID()
- Details
-
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.
