  "description": "In the Linux kernel, the following vulnerability has been resolved:  hfsplus: return error when node already exists in hfs_bnode_create  When hfs_bnode_create() finds that a node is already hashed (which should not happen in normal operation), it currently returns the existing node without incrementing its reference count. This causes a reference count inconsistency that leads to a kernel panic when the node is later freed in hfs_bnode_put():      kernel BUG at fs/hfsplus/bnode.c:676!     BUG_ON(!atomic_read(\u0026node-\u003Erefcnt))  This scenario can occur when hfs_bmap_alloc() attempts to allocate a node that is already in use (e.g., when node 0\u0027s bitmap bit is incorrectly unset), or due to filesystem corruption.  Returning an existing node from a create path is not normal operation.  Fix this by returning ERR_PTR(-EEXIST) instead of the node when it\u0027s already hashed. This properly signals the error condition to callers, which already check for IS_ERR() return values.",
